UF20.241

PULS UF20.241 is an Uninterruptible Power Supply (UPS) control module, part of the UF-series, designed as a buffer module with capacitor storage featuring a green status LED. This product is housed in aluminum and utilizes spring-clamp connections for secure installation. It measures W64mm x H124mm x D102mm and is designed for DIN rail mounting. The UF20.241 operates with a supply voltage range of 19.2Vdc to 30Vdc, with a nominal voltage of 24Vdc, and supports a rated current of 20A before fusing. It is engineered to function within an ambient air temperature range of -25 to +70°C and is suitable for DC networks. The module includes a visual position indicator for Ready, Buffering, and Inhibit statuses. It offers protection functions including output overvoltage protection, with typical protection at 32Vdc and a maximum of 35Vdc. The UF20.241 allows for parallel connection of buffer modules to enhance output ampacity or hold-up time. It delivers a fixed output voltage of 24Vdc, boasts an efficiency of 0.99 with a 24Vdc input, and provides a hold time of 31ms / 0.31s at a 20A load. Power dissipation is calculated at 1.9 W for a 24Vdc input at 20A output current, with a ripple of 200mVpp across a frequency range of 20Hz to 20MHz at 50Ω. Its electrical durability is rated at 166,000 hours in standby mode at 40°C and 469,000 hours at 25°C.
