3. Functional Overview
The 36kW Diamond power supply contains two 18kW power modules. Each 18kW power module
contains a boost converter and a buck converter. The boost converter works in current mode
control to provide power factor correction. The output of the boost converter provides power to
the buck converter. The buck converter provides the power supply output with current or voltage
regulation modes. Control of both converters is tightly coupled with a digital control system.
The power supply comes with a remote control panel. The standard remote control panel has a
volt meter, amp meter, status indicators, function buttons, and digital encoders to adjust settings.
The optional graphic touch screen control panel provides an intuitive graphical user interface with
easy access to menus and power supply settings. Both control panels provide digital control
signals, a serial host port, and an optional analog control card for external control.
This switch mode power supply provides DC, pulse, or complex waveform outputs. The DC and
pulse settings can be adjusted using the control panel. Complex waveforms are designed using
the provided computer software application. Multiple complex waveforms can be downloaded to
the control panel and then selected to run using the control panel menus.
The following is a general list of features.
DC, Pulse, or custom waveform output
Programmable ramp output (waveform amplitude ramp)
Manual Cycle Control
Real Time Cycle Control (RTC)
Amp Time Cycle Control (ATC)
User Configurable Totalizer(s) (one per output channel)

inverter systems or systems with a
reversing bridge. (Shipped with
required cables if applicable).
5.3. Output Power Connections
Output bus bars have holes for two separate ½ inch bolts that need to be connected in parallel or
series depending on the system configuration. The connection to the load should be of
appropriate cross sectional area so as not to heat the power supply output connections.

Page 16 of 146 198-1600-00 Rev F
5.4. Digital I/O
The 8 pin connector on the remote control contains all of the digital inputs and outputs.
The digital input (operate control) is activated by a contact closure on the digital input + and –
connections.
A series of digital outputs are available to provide status information for process control. Each
output is an open collector output. The output should be used to switch no more that 24VDC and
no more than 35mA. Polarity of the connections should be observed. It is the customer’s
responsibility to ensure any circuit connected to the digital outputs meets the above criteria.
Failure to stay within the specified maximum ratings will result in damage to the digital outputs.
5.4.1. Digital Inputs
5.4.1.1. Remote Operate Control Connections
The operate/standby state can be controlled by the remote operate input. Pins 7 and 8 of the
eight pin connector on the remote control are used for remote operate control. Shorting pins 7
and 8 together activates the operate input. The operate input is configurable; see 6.3.6 Remote
Operate/Standby Control (Digital Input) for details.
5.4.2. Digital Outputs
5.4.2.1. End Of Cycle Status Connections
Digital output pins 1(+) and 2(-) can be used to sense when the end of a timed cycle (ATC or
RTC) has been reached. The output will switch on to indicate the end of a cycle. If the power
supply contains more than one output channel the output is activated when any of the output
channels has reached the end of a cycle, there is not a separate output for each channel. For
remote sense of the end of cycle for individual output channels the serial host port interface
should be used.

5.4.2.2. Alarm/Fault Status Connections
Digital output pins 3(+) and 4(-) can be used to sense the presence of one or more alarm
conditions. When one or more alarms are active (the remote control fault lamp will also be on) the
alarm output is switched on. To remotely detect the presence of specific alarms or fault conditions
use the serial host port interface. The details of what each alarm code indicates and how it can be
cleared can be found in Appendix C: Error Codes.
5.4.2.3. Operate Status Connections
Digital output pins 5(+) and 6(-) can be used to sense when the power supply is operating. The
output will switch on when the power supply is operating. If the power supply contains more than
one output channel the output is switched on when any of the output channels is operating. For
remote sense of the operate state for individual output channels the serial host port interface
should be used.

5.5. Serial Host Port Connections
The serial host port can be used to monitor and/or control the power supply using the ASCII Host
Protocol (See section 7:Remote Host Control). The serial host port supports a half duplex
RS485 interface. Multiple power supplies can be connected to a single RS485 bus (multi-drop).
Each device on the RS485 bus is individually addressed using the ASCII Host Protocol. If an
RS232 device (such as a PC) will be connected to the host port then an RS232 to RS485
converter module will be required (not included).
5.6. Inverter Control Connections
The remote control is connected to the main power supply inverter with the supplied DB9 cable.
Various standard and custom cable lengths are available from Dynatronix. Only use cables
provided by or specified by Dynatronix. Improper connections or cable lengths and wire gauges
can result in un-reliable operation or damage to the remote control or inverter control.

5.7. Analog Card Connections (Optional 138-0471-XX Card)
Rectifiers which have optional analog control will be equipped with the 138-0471-xx card and
require customer supplied wiring. See the wiring diagram figures below for connection information.
The following give a description of the control and read back signals on the 12 pin terminal strip.
VOLTAGE CONTROL (VC)
Control of the power supply output voltage can be achieved by connecting the appropriate signal
to pins 6 (+) and 5 (-).
CURRENT CONTROL (CC)
Control of the power supply output current can be achieved by connecting the appropriate signal
to pins 8 (+) and 7 (-).
VOLTAGE READBACK (VRB)
Monitoring of the power supply output voltage can be achieved by connecting the appropriate
sensing circuitry to pins 9 (+) and 10 (-).
CURRENT READBACK (CRB)
Monitoring of the power supply output current can be achieved by connecting the appropriate
sensing circuitry to pins 11 (+) and 12 (-).
Pin 3 can be used for a DC COMMON connection.
Pin 1 can be used as a connection point for the cabling shields.
NOTE: To reduce the possibility of electrical noise interfering with the proper operation of the
control system, use shielded twisted pair for all wiring between the analog controller and the
power supply. Belden™ 8761 or equivalent cable type is recommended.
NOTE: The shielding for the voltage & current control lines should be earth grounded at the
controller and should be cut-off at the power supply. The shielding for the voltage & current read
back lines should be earth grounded at the power supply (pin 1 - SHIELD) and cut-off at the
controller. See diagrams below.
NOTE: When using 4-20mA control, the controller’s input channels must be isolated from each
other. It is recommended that isolated receivers (ex. OPTO 22 AD3T or equivalent) be used with
the curr rd out and volt rb out transmitter channels. These transmitter channels are self powered.
The receiver inputs and transmitter outputs are ground isolated from the power supply’s
DC common and are isolated from earth ground as well. However, be aware that both
input channels and both output channels of the AI board, do share a common signal
ground. In other words, there is no isolation from channel to channel or receiver inputs
to transmitter outputs except that provided by the differential inputs. A common ground
signal from the analog controller is required.
NOTE: MAXIMUM LOOP RESISTANCE THAT CAN BE IN SERIES BETWEEN THE (+) AND (-)
OF THE CURRENT OR VOLTAGE READBACK IS 400 OHMS
