DESCRIPTION
The RMF-4012 has an auto range voltage input of 85 to 264 VAC, with 47 to 63 Hz or 120 to 370 VDC. This unit comes with
three available outputs that are adjustable; these outputs are available in 12, 24, and 48 VDC. All RMF devices have a built-in TTL
remote control and remote sense along with a DC-OK TTL signal, along with short circuit, over load, over voltage, over temperature
protections, and hold UL, CE, TUV, CUL approvals. To guarantee DuraComm’s durability DuraComm offers a 3 year warranty for all of
their RMF series products.
