DIN UPS power supply family now with higher power models

The new Series, which has been introduced in response to the security industry’s demand for higher power capability, currently consists of two models with different output voltage levels. Both units are highly reliable and can be assembled on TS35/7.5 or TS35/15 DIN rails within an industrial cabinet.

The units both have universal inputs which accept 90 – 264Vac or 127 - 370Vdc. The DRC-100A has two 13.8V outputs, and DRC-100B delivers 27.6V from its two outputs. These are suitable for 12V and 24V batteries respectively.

With efficiencies up to 89 percent, both models feature a fanless design with cooling by free air convection. Protection functions include overload, over-voltage, battery low cut off and fused battery reverse polarity safeguard; the units also have relay contact alarm signals for AC OK and battery low. An LED indicator shows Power On status.

An external 12V or 24V battery can be connected to the secondary output contacts provided on the power supplies. During normal operation with AC mains present, the power supplies rectify and filter the incoming AC to supply DC power to the load and charge the battery.

During a mains failure, the battery ensures continued power to the load until it is discharged or mains power is restored. The battery charger floats on the rectifier’s dc output, ensuring seamless transfers between rectified mains and battery supplies, and uninterrupted power to the load.
