■ Model Encoding

■ Description

DRC-40 is a 40W AC/DC DIN rail type security power supply series. In addition to the primary output, there

is a charger output with a smaller rated current, enabling the backup power supply application the security

access systems require. DRC-40 accepts the universal input between 90VAC and 264VAC, and supplies

13.8VDC and 27.6VDC at output, respectively. With the efficiency up to 87%, it can operate with air

convection cooling under -30 through 70 . In addition to the key protection features such as overload ℃℃

protection, over voltage protection, battery low cut off, and battery reverse polarity protection (by fuse),

the alarm signal for AC OK and battery low signaling is provided, via TTL open collector output for the

standard model ( via relay contact output as the optional model), to facilitate the system design.
