<1.0 V. In addition, the voltage at the output terminals must be limited to
29.4V.
Remote Voltage Programming 1000 ohms per volt for resistor connected between pins 1 and 2
external resistor. on TB201 (see Figs. 4 and 5).
Remote Voltage Programming Volt per volt for voltage source connected between pins 1 and 2
external voltage source. on TB201 (see Figs. 4 and 5).
Remote On/Off Control Enable/Disable output via TTL compatible signal connected between
pins 6 and 7 of “D” connector (see Fig. 9).
Signals Isolation Pins 6 and 7 are fully isolated from all other power supply terminals.
Signal Logic Logic zero (below 0.7 V), short circuit or open circuit disables power
supply output. Logic one (above 2.5 V) enables power supply output.
Signal Current Draw Current draw from Logic 1 input is less than 4mA.
Output Response Time Output will be within specified limits within 100 ms. of application of
logic “1” signal.

GUIDE TO APPLICATION
4.1
SAFETY NOTICE
Dangerous voltages exist in this equipment. Observe the usual safety precautions when operating,
wiring, or servicing to reduce the risk of shock or injury.
4.2
INPUT VOLTAGE
See Table 3 on page 4.
4.3
OUTPUT VOLTAGE
This power supply operates as a constant-voltage source with maximum load ratings as listed on
page 3. If the load current tries to exceed 110% of the 60°C rating, the output voltage will begin
to decrease, thereby limiting the power delivered to the load. Upon removal of overload, normal
operation will resume.
When shipped from the factory, the power supply is ready for use with output voltage (Vout) set to
its nominal rating of 24.0V. Jumpers are in place on TB201 for local voltage sensing. Where
precise regulation is required directly at the load, remote voltage sensing can be utilized. This
can be achieved by utilizing the remote sense terminals on TB201 or "D" connector (see Figs.2
and 3). The output voltage can be increased by turning the Vout adjust potentiometer clockwise.
The output voltage is decreased by turning the Vout adjust potentiometer counter clockwise.
As shown on page 4, LZS-A1500 power supplies have both a maximum current rating and a
maximum output power rating (as a function of ambient temperature and input voltage). Care
should be taken to limit both output current and output power to be within specified limits. If
these limitations are not adhered to, the internal thermal protection circuit may shut down the
power supply's operation. For remote voltage sensing, the maximum limits for output power, as
given on page 4, apply at the power supply output terminals, not at the remote sensing point.
When adjusting the output voltage above 24.0V, ensure that there is sufficient OVP margin with
respect to the output voltage, to avoid nuisance tripping.
4.4
OVERVOLTAGE
PROTECTION CIRCUIT ADJUSTMENT
The overvoltage protection circuit provides an adjustable means of disabling the DC output if it
should exceed a pre-determined safe value. When shipped from the factory, the overvoltage
level on each LZS unit is set as given in table 7 on page 5. If a different OVP threshold is
required, it can be adjusted using the following method:
1. Turn the OVP Adjust potentiometer fully clockwise (at least 10 turns).
2. With the power supply unloaded, set Vout to the OVP threshold desired. In cases where the
desired OVP threshold exceeds the unit’s adjustment range maximum of 29.4V, a programming
resistor (see figures 4 & 5) will temporarily be needed to provide the higher output voltage to
perform the adjustment. Once adjusted, remove the programming resistor. Alternatively, you may
use an external voltage source to set the OVP threshold as shown in figures 4 & 5.
3. Slowly turn the OVP adjust control counter clockwise while monitoring the output voltage. Stop
turning the control immediately when the red FAULT indicator lights, indicating an OVP shutdown.
At that point, the OVP threshold is set to the desired value.
4.5
OVERTEMPERATURE AND OVERVOLTAGE SHUTDOWN
LZS-A1500 power supplies will automatically shut down if operating conditions cause excessive
internal heating or excessive output voltage. After the occurrence of an overvoltage shut down,
input power must be interrupted or the remote on/off feature must be toggled to re-establish the
output. Overtemp shutdown resets itself once the unit has cooled off by approximately 10°C.
4.6
AUXILIARY CONTROL AND ALARM SIGNALS
LZSa power supplies provide auxiliary control and alarm signals per page 5. These signals are
accessible via the15-pin, sub miniature "D" connector, located below the output terminals of the
unit.
