Specifications
The following table lists technical specifications for the CKM-FPO75
power supply.
DC1 Output (TB1) The main DC output of the power supply. The full current of the
power supply is available on these terminals at all times and is
unaffected by the FAI input. These terminals accept AWG12 –
AWG18 wire.
IMPORTANT: When powering magnetic loads, such as maglocks,
door strikes, solenoids, and so on, each of these loads must have a
reverse protection diode either built-in or external to the device.
DC2 Output
Configuration
(F2 and F3)
Select the appropriate fuse holder for the DC2 fuse to choose fail-
safe or fail-secure operation of the DC2 output.
• DC2+ NO (F2) – the DC2 output energizes when an FAI signal is
received on the FAI input.
• DC2+ NC (F3) – the DC2 output de-energizes when an FAI
signal is received on the FAI input.
If you are not using the FAI input, place the DC fuse in the DC2+
NC fuse holder to use the DC2 output as a second power output.
Do not install fuses into both fuse holders simultaneously.
DC1 (D4) – Green Lights when voltage is available on the DC1 output terminals.
Output Voltage
Selection (SW1)
Selects the output voltage of the CKM-FPO power supply.The
voltage settings are labeled on the PC board as follows:
•12
–12 VDC nominal out
•24
–24 VDC nominal out
Important: Remove power before changing output voltage or
damage to the power supply may occur.
