1 INTRODUCTION
The Switching Power Supply Series offers compact, lightweight, highly efficient and reliable units that are
DIN Rail-mounted or mounted on the back of a panel. Short circuit and overload protection is provided as
well as over-heat protection to stop output when the temperature reaches 275°[135°C]). Units also have
soft-start functionality to limit peak current and voltage during startup. Two special functions are
provided: Remote Control Switching (RPS) and Uninterruptible Power Supply (UPS).
The following models are included in the Switching Power Supply Series.

3 GENERAL OPERATION
Figure 3 – General Operation
1. For output and short circuit protection, ensure that the Switch/Short Circuit jumper block is
installed and properly seated.
2. Adjust the current (using Potentiometer A) for maximum load current protection by rotating fully
clockwise.
3. Connect the power (100-240 VAC / 140-340 VDC).
4. Adjust the output voltage (using Potentiometer V) to 24 VDC.
5. Connect the load to the output terminal.
4 Remote Control Switching (RPS) Function
The RPS function allows the control of the output voltage using a remote control switch.
Figure 4 –RPS Function
1. Remove the Switch/Short Circuit jumper block. Wire an external switch (K1).
2. Adjust the current (using Potentiometer A) for maximum load current protection by rotating fully
clockwise.

3. Connect the power (100-240 VAC / 140-340 VDC).
4. a. Close switch (K1) to turn power ON from the supply.
b. Adjust the output voltage (using Potentiometer V) to 24 VDC.
c. Open switch (K1) to turn power OFF from the supply.
5. Connect the load to the output terminal.
7. Close switch k1 to turn power ON from the supply.
5 Uninterruptible Power Supply (UPS) Function
The UPS function uses an external battery to provide power in the event that the power source stops
providing power or is interrupted.
Figure 5 –UPS Function
1. For output and short circuit protection, ensure that the Switch/Short Circuit jumper block is
installed and properly seated.
2. Adjust the current (using Potentiometer A) for maximum load current protection by rotating fully
clockwise.
3. Connect the power (100-240 VAC / 140-340 VDC).
4. Adjust the output voltage (using Potentiometer V) to 24 VDC.
5. Disconnect the AC/DC power wire.
6. Wire switch K2 and fuse wire F1 and the External Battery
7. Re-connect the power (100-240 VAC / 140-340 VDC).
Note: If the battery voltage is over +24 VDC, adjust Potentiometer V to the applicable voltage.
Note: When using the UPS function, the output is normally powered by the line voltage. When the line
and battery are connected, the battery will be charged. If the line voltage is removed, the output is
supplied by the battery. Switch K2 allows the battery to be disconnected, and fuse F1 protects the battery
side of the circuit. The battery current is ≤3 A.
Warning: Be sure to wire the load observing the proper polarity on the unit and ensure that the
maximum working current is ≤3 A.
Warning: Be sure to wire switch K2 and fuse wire F1 and the External Battery observing the proper
polarity on the unit.

7SAFETY
When found on the product, the following symbols specify:
Warning: Consult user documentation. Warning: Electrical Shock Hazard.
WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the power. Be sure to locate fuses as close to the source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against risk of
fire and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not clear by replacing the fuse.
WARNING: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or
loss of life.

•All applicable codes and standards need to be followed in the installation of this product.
•For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG or
larger.
Adhere to the following safety precautions whenever any type of connection is made to the module.
•Connect the green safety (earth) ground first before making any other connections.
•When connecting to electric circuits or pulse-initiating equipment, open their related breakers. Do
not make connections to live power lines.
•Make connections to the module first; then connect to the circuit to be monitored.
•Route power wires in a safe manner in accordance with good practice and local codes.
•Wear proper personal protective equipment including safety glasses and insulated gloves when
making connections to power circuits.
•Ensure hands, shoes, and floor are dry before making any connection to a power line.
•Make sure the unit is turned OFF before making connection to terminals. Make sure all circuits
are de-energized before making connections.
•Before each use, inspect all cables for breaks or cracks in the insulation. Replace immediately if
defective.
