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.

Verified stock: 4

PULS CP10.241 is a DIN rail mounting power supply unit housed in an aluminium casing, designed to operate within an ambient air temperature range of -25 to +70°C. It features a net width of 39 mm and offers a degree of protection rated at IP20. The unit consumes current at rates of 1.13A with a 230Vac input, 2.15A with a 120Vac input, 2.6A with a 100Vac input, and 2.35A with a 110Vdc input for a 24Vdc / 10A output, with peak inrush currents of 11A and 7A for 230Vac and 120Vac inputs respectively. Efficiency rates are noted at 0.952 for 230Vac input and 0.936 for 120Vac input. Dimensions are specified as W39mm x H124mm x D117mm. The unit exhibits a start-up delay of 240-300ms for 100-230Vac input, with rise times of 30ms and 160ms under specified conditions. It includes protection functions against output overvoltage, overload/short-circuit, and over-temperature, with automatic restart features. Series or parallel operation is supported for increased output voltages or power, including 1+1 redundancy with a redundancy module. The unit is resistant to back-feeding loads up to 35V. Power dissipation/losses are 12.1W and 16.4W for 230Vac and 120Vac inputs respectively, with an output stage capacitance of 4400µF. Electrical durability spans from 75,000 to 499,000 hours under various conditions. Ripple is maintained at 50mVpp. This AC/DC power supply unit, part of the CP-series, is designed with ATEX approval, a 20% power reserve, and a DC-OK relay contact output. Connection is facilitated via screw-clamp connections. Supply voltage ranges from 88Vdc-180Vdc for DC and 85Vac-264Vac for AC, with specific tolerances for overvoltage and shutdown voltages. Rated current is 12A at 48Vdc in temperatures up to +45°C, with adjustments for higher temperatures. It operates on a single-phase (1AC) or DC network, providing a rated power of 288W at -25 to +45°C, 240W at -25 to +60°C, and 180W at +70°C, with a linear derating between +60°C and +70°C. The output voltage is adjustable between 24Vdc and 28Vdc, featuring a 200mV turn-ON overshoot and a hold time of 37ms at 120/230Vac input.
