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.

The individual user should take care to determine, prior to use or installation, whether this device is suitable, adequate or safe
for the use intended. Since individual applications are subject to great variation, DuraComm makers no representation or warranty as
to the merchantability, suitability or fitness of these units for any specific application.
The precision regulated power supplies operate internally from voltages in excess of 300 volts. In rare cases, voltage spikes
or transients on the AC power line, or overheating, may cause a component failure in the power supply. Overloading the output will
cause the over current feature to operate. In either case, the cause must be determined and corrected. Failures require investigation
as to cause and/or repair of the unit.
THERE ARE NO USER SERVICEABLE PARTS INSIDE. HAZARDOUS VOLTAGES EXIST INSIDE THE UNIT. SERVICE AND
REPAIR MUST BE REFERRED TO QUALIFIED FACTORY PERSONNEL.
INSTALLER NOTES
The outputs are NOT referenced to the chassis. The Modular System can be used either positive or negative ground.
DO NOT block any of the cooling vents on the sides and always allow adequate ventilation by not installing the unit inside
tightly closed spaces. Physical mounting position is not critical but the cooling vents and the load controlled cooling fan must not be
blocked.
AC MAIN OPERATING INPUT VOLTAGE
The AC input is auto-ranging and will operate without adjustment from 85 VAC to 264 VAC. Maximum efficiency is realized
with input voltages above 180 VAC. Linear de-rating to ~85% @ 90 VAC is recommended for AC inputs less than 180 VAC.

CONDUCTOR ATTACHMENT
The DC output terminals are 6mm diameter and a ¼ inch ring terminal will fit exactly. The ¼ inch ring terminal may be
crimped or soldered to the conductors before attaching to the DC output terminals. DO NOT solder the ring terminals while on the DC
output studs. Use a 10 mm wrench to securely tighten the hex nut on the stud.
