Description

Delta PMU-27V155WCCA is a buffer power supply with an output voltage of 27V (24 - 28V DC) and a power of about 151 W. The device is distinguished by high work efficiency and reliability. In the event of a mains power failure, the PSU automatically switches to accumulator (battery) power. The product has numerous protections: against overdischarge, against reverse battery connection, against overvoltage, against overload or against overheat. The power supply allows you to select the battery charging current, the range is: 0.5 - 1.5 A.

Othe offered product has two LEDs indicating the power supply (DC OK - green color) and reverse battery connection (red color), it also allows you to connect LEDs indicating AC power and low battery charge. The power supply meets numerous safety standards and is distinguished by a fast AC to DC switching time. The device is covered by a 5-year warranty.

The most important features:

output voltage - approx 27 V (24 - 28 V);
output power - 151 W;
regulation of battery charging current - 0,5 - 1,5 A;
overdischarge protection;
the power supply meets numerous safety standards;
5-year warranty.
