Nominal Input Voltage
230 VAC or 120 VAC (jumper selectable)
Nominal Output Voltage
24 VDC
Maximum Output Current
(isolated)
0.7 A
Protective Circuitry
Inputs
Self-restoring fuse
Outputs
Overvoltage protection: limited by a transzorb diode (type:
SM6T30A)
Overload protection: by thermal current limiting (should the
thermal current limiting respond, the input voltage must be
switched -- off/on for reactivation).
