The M4500, M4501, M4508 thru M4513 are powered by a separate external power supply. Input power to these modules is +5VDC, +12VDC, and -12VDC. The P4500 power supply can be used with all these modules to provide the voltages required. Input power to the P4500 is 50-60HZ, 100 to 240 VAC at 0.45 to 0.25 Amps respectively. The output current of the P4500 is rated at 3.0Amps (+5VDC), 0.5Amps (+12VDC), and 0.5Amps (-12VDC). The P4500 is connected directly to the M45XX module with a five pin JST connector on the front of the M45XX module.

The M4502 and M4503 incorporate a built-in power supply and are thus powered directly from 50-60HZ, 100 to 240 VAC at 0.45 to 0.25 Amp power.
