Product Description
Samlex SEC-1235M 30 Amp Switching Power Supply
This high efficiency UL-60950-1 approved AC-DC power converter provides a highly regulated output DC voltage of 13.8 Volts at 30 Amps with an AC input of 120 Volts, 60 Hz (230 Volts, 50 Hz possible by internal jumper setting). These advanced switch-mode DC power supplies were designed specifically for land mobile radio applications. The power supplies produce clean reliable power and are highly filtered to suppress RFI. The unit comes with front panel ammeter and voltmeter and a detachable power supply cord with NEMA 5-15P plug. Features include over-load, short-circuit, over-temperature and over voltage protection. The AC-DC power supply conforms to FCC Part 15(B), class B digital device.
