DC Power Supplies
CJ1W-PD025 Power
Supply Unit
DC Power Source Supply 24 V DC.
Keep voltage fluctuations within the specified range (19.2 to
28.8 V DC).
Power Supply Capacity The maximum power consumption is 50 W per Rack, but there will be a surge
current of about five times that level when the power is turned ON.
Crimp Terminals The terminals on the Power Supply Unit are M4, self-raising terminals with
screws. Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Tighten the terminal block screws to the torque of 1.2 N·
m. Use crimp terminals (M4) having the dimensions shown below.
Note 1. Be sure not to reverse the positive and negative leads when wiring the
power supply terminals.
2. Supply power to all of the Power Supply Units from the same source.
3. Do not remove the protective label from the top of the Unit until wiring has
been completed. This label prevents wire strands and other foreign matter
from entering the Unit during wiring procedures.
4. Do not forget to remove the label from the top of the Power Supply Unit af-
ter wiring the Unit. The label will block air circulation needed for cooling.
