WARNINGS AND CAUTIONS

BOP 36-28MG2/21/08 E

PAGE WARNING/CAUTION

3-19 WARNING: For inductive loads, and especially superconducting magnet type loads,

the inherent offset of the BOP in the OFF state may generate significant

current in the circuit. A properly rated switch in parallel with a resistor

must be connected between the power supply and the load. The switch

must be open and the BOP front panel LCD must read 0V, 0A before re-

moving or installing connections between BOP and load.

3-19 WARNING: For both inductive loads and constant-current-type active electronic

loads when the BOP output is set to OFF, a path is provided for absorbing

either the energy accumulated in the reactance of the load during the ON

state, or energy delivered by an electronic load. This prevents damage to

the load and power supply as well as providing safety for the user. How-

ever, In addition to the built-in safety features, constant-current-type ac-

tive electronic loads must be adjusted to zero and the BOP front panel

LCD must read 0V, minimum current, before handling the power supply-

to-load connections.

3-19 WARNING: Accessing the BOP after the output is disabled in BATTERY mode is haz-

ardous because (1) high current arcing is possible and (2) either the ex-

ternal battery voltage, or the voltage (±Voltage Protection max) on the

BOP output terminals may be dangerous. Therefore, for battery and con-

stant-voltage-type active electronic loads it is recommended that two

properly rated external switches be installed for safety: one in series with

the battery, and one across the BOP output. After the unit is set to OFF,

first open the switch is series with the battery, then close the switch

across the BOP output to ensure safety before handling BOP connec-

tions. When connecting the battery, the switch across the output should

be opened after the connections are complete and then the switch in se-

ries with the battery should be closed. If the constant-voltage-type active

electronic load is adjusted to zero before handling the power supply-to-

load connections, only the switch across the BOP output is required.

3-28 WARNING: Be sure that output power is OFF (Standby indicator lit) while connecting

monitoring device. Be sure that connections are secure and that termi-

nals are not inadvertently shorted.

4-8 WARNING: The sense resistor will be dissipating full rated current of the BOP. If it is

hot to the touch, the sense resistor value, power rating and/or cooling are

incorrect; refer to PAR. 4.3 and Table 4-2.

4-14 WARNING: The sense resistor will be dissipating full rated current of the BOP. If it is

hot to the touch, the sense resistor value, power rating and/or cooling are

incorrect; refer to PAR. 4.4 and Table 4-2.

2-3 CAUTION: When an external shut-down signal is sent to the unit, the shut-down con-

dition is latched and the red FAULT indicator on the front panel is ON. To

resume normal operation it is necessary to cycle power off, then on (pre-

ferred) or briefly press the RESET key on the front panel.

2-6 CAUTION: it is recommended that source power of external equipment connected to

the Analog Port be applied through an isolating transformer To avoid

ground loops or possible damage to the BOP due to incorrect equipment

a-c wiring (e.g., defeating of ground connection).

2-8 CAUTION: The rack must provide support at the rear (within 6 inches of the rear pan-

el). Optional slides can also be used (see PAR. 2.4.2).

FBOP 36-28MG2/21/08

LIST OF

WARNINGS AND CAUTIONS

PAGE WARNING/CAUTION

2-8 CAUTION: When working with active loads, the voltage or current of the active load

must not exceed the maximum voltage or current rating of the BOP. Oth-

erwise the overvoltage or overcurrent protection will shut down the pow-

er supply.

2-10 CAUTION: Never connect the load to the sense terminals. Monitoring instruments

(e.g., DVM, etc.) are the only external equipment that may be safely con-

nected to the sense terminals.

2-10 CAUTION: The safety features incorporated into the BOP to handle energy from Ac-

tive loads are unable to protect the power supply or the load if input pow-

er to the BOP is lost or if the BOP Malfunctions. It is recommended that

the user monitor “Power OK” flag pins 3 and 4 of the external Protect Port

(see Table 2-4) and implement a fast-acting means of disconnecting ca-

pacitive loads or crowbarring inductive loads to prevent damage to both

the BOP and the load in the event of input power loss.

2-13 CAUTION: For parallel configurations, Remove links between (COM S) and (COM

OUT) terminals of all slaves to prevent damage to the unit and maintain

system accuracy.

2-13 CAUTION: Connecting multiple units to different a-c input sources may damage the

BOP power supplies and/or the load.

2-19 CAUTION: The units are now configured as slave(s) to be controlled only by the master.

Do not use the slave keypad, RS 232 port or GPIB port to try to control the

slave(s).

3-3 CAUTION: Pressing RESET will cause voltage transients to appear at the output

which may damage a connected load.

3-12 CAUTION: When the ADJUST control is rotated, the active parameter is immediately

effective if the output is enabled (on = STANDBY indicator not lit). The

voltage/current applied to the load changes as the ADJUST control is ro-

tated.

3-18 CAUTION: When working with active loads, always adjust the BOP protection limits

to be above the maximum values of voltage or current expected from the

load. For example, when the BOP is operating in voltage mode sinking

energy from a constant current type load, set the current protection limits

of the BOP above the maximum current expected from the load.

3-24 CAUTION: Before Pressing @to enter the Saved Waveform Screen from the power-

up screen, perform the following steps to avoid unexpected voltages or

currents from previous settings being briefly applied to the load when the

waveform is first executed.

3-33 CAUTION: Pressing RESET will cause voltage transients to appear at the output

which may damage a connected load. Switch is recessed to prevent inad-

vertent activation.

3-50 CAUTION: When the serial port has received an XOFF, the error message -400, QUE

error will be placed in the queue to indicate the loss of transmitted infor-

mation due to a received XOFF character. When XON is received, the unit

will transmit all data in it's buffer followed by the exclamation character

(!). This (!) character is not part of any message from the BOP and indi-

cates the transmission buffer has been cleared and the BOP is idle.

4-12 CAUTION: If the CALIBRATE ZERO !function is available, perform this function

first, as it affects all other output calibrations.

SECTION 1 - INTRODUCTION

1.1 SCOPE OF MANUAL

This manual contains instructions for the installation, operation and servicing of the BOP series

of 1000 Watt rack-mounted, 4-quadrant bipolar, programmable, voltage and current stabilized

d-c power supplies manufactured by Kepco, Inc., Flushing, New York, U.S.A.

NOTE:This manual does not apply to units with Firmware Rev less than 2.0.

1.2 GENERAL DESCRIPTION

The BOP Series (Figure 1-1), hereafter referred to as BOP, are true 4-quadrant programmable

voltage and current power supplies, meaning they are capable of both sourcing and sinking

power. These bipolar power supplies pass smoothly through zero without switching to provide

true ± voltage and ± current. These BOP power supplies use switch mode technology for low

dissipation. A bi-directional, isolating, a-c input power factor correcting (PFC) circuit recuperates

energy sinked from an active load and sends it back into the line to maintain low dissipation.

These BOP power supplies are controlled digitally from a menu-driven front-panel keypad or

one of the standard remote digital interfaces (GPIB or RS 232) to set voltage and current and

the four protection limits (+voltage, –voltage, +current and –current.) A front panel rotary

adjuster allows real-time adjustment of the output. A large LCD displays the settings, mode and

the actual output voltage and current. Additionally, these BOP models can be remotely con-

trolled by an analog ±10V input for the main channel (voltage or current), and a +1 to +10V input

for the limit channels.

BOP models are suitable for driving inductive loads such as large magnets or motors, and for

exercising batteries. They are also suitable for characterizing solar cell arrays, and powering

many electrochemical reactions.

1.3 SPECIFICATIONS

Table 1-1 below indicates parameters that vary for different 1000 Watt BOP models; Table 1-2

lists general specifications that apply to all 1000 Watt BOP models.

BOP 100-10MG ±100V d-c ±10A d-c 10.0 1.0

NOTE: When connecting active loads, the steady-state voltage of the active load must not exceed the maximum

voltage rating of the BOP. Otherwise the overvoltage protection will shut down the power supply.
