UF20.481
Puls
Product Lifecycle: Active
PULS UF20.481 is an Uninterruptible Power Supply (UPS) control module, part of the UF-series, designed as a bfr. module with capacitive storage and features a green status LED. It is housed in aluminium and utilizes spring-clamp connections for connectivity. This module measures W64mm x H124mm x D102mm and operates on a supply voltage range of 38.4Vdc to 60Vdc, with a nominal voltage of 48Vdc. It is rated for a current of 20A (bfr.) and is designed for DIN rail mounting. The UF20.481 can operate in ambient air temperatures ranging from -25 to +70°C and is suitable for DC networks. It includes a visual position indicator for Ready, Buffering, and Inhibit statuses. The module offers protection functions including output overvoltage protection, with typical protection at 58Vdc and a maximum of 60Vdc. Buffer modules can be connected in parallel to increase output ampacity or hold-up time. It provides a fixed output voltage of 48Vdc, boasts an efficiency of 0.99 at 48Vdc input, and offers a hold time of 15ms / 0.15s at a 20A load. Power dissipation/losses are 1.9 W at 24Vdc input with 0A output current. Ripple is specified as 250mVpp at 5A, 400mVpp at 10A, and 600mVpp at 20A, across a frequency range of 20Hz to 20MHz at 50Ω. Its electrical durability is rated at 161,000 hours at 40°C and 457,000 hours at 25°C in standby mode.
