DRC-40 (40W) and DRC-60 (60W) power supplies can mount to TS-35/7.5 or TS35/15 DIN rails. In addition to their primary output, both models provide a secondary output designed for use with battery chargers. Together with an external battery, this can facilitate a security power system with a DC UPS function. These devices accept either a 90VAC to 264VAC full range input or a 127VDC to 370VDC input, and each comprises two models with different DC output voltages: 13.8V and 27.6V. All models operate with a working efficiently of up to 88%, which allows an operating temperature range of -30°C to +70°C, while needing only free air convection cooling. The DRC-40 provides AC OK and battery low alarms using TTL outputs or, optionally, relay contacts. The DRC-60 provides these alarms through relay contacts.
