Product description

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.

PULS CP10.241-C1 is a DIN rail mounting power supply unit with an aluminium housing designed for a wide range of industrial applications. It operates within an ambient air temperature range of -25 to +70°C and has a net width of 39mm. The unit consumes 1.13A at 230Vac input, 2.15A at 120Vac input, 2.6A at 100Vac input, and 2.35A at 110Vdc input for a 24Vdc / 10A output, with peak inrush currents of 11A at 230Vac input and 7A at 120Vac input. It offers an efficiency of 0.952 at 230Vac input and 0.936 at 120Vac input. The CP10.241-C1 features IP20 degree of protection and is resistant to harsh environments due to its conformal coated PCB. Its dimensions are W39mm x H124mm x D117mm. The unit has a start-up delay of 240-300ms and a rise time of 30ms to 160ms depending on the load capacitance. It includes protection functions such as output overvoltage, overload/short-circuit, and over-temperature protection with automatic restart. The power supply supports series/parallel operation for increased output voltages or power, and 1+1 redundancy with a redundancy module. It can handle back-feeding loads up to 35V without malfunctioning. Power dissipation/losses are 12.1W at 230Vac input and 16.4W at 120Vac input, with an output stage capacitance of 4400µF. Electrical durability ranges from 39,000 to 499,000 hours depending on the operating conditions. The ripple is 50mVpp across a 20Hz to 20MHz range. This AC/DC power supply unit is part of the CP-series, featuring ATEX approval, conformal coating, 20% power reserve, and a DC-OK relay contact output. It uses screw-clamp connections and accepts a supply voltage of 88Vdc-180Vdc or 85Vac-264Vac, with specific tolerances for overvoltage and shutdown voltages. The rated current is 12A at 48Vdc in temperatures up to +45°C, decreasing to 7.5A at 24Vdc at +70°C. It is suitable for single-phase (1AC) or DC networks, 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 from 24Vdc to 28Vdc, with a 200mV turn-ON overshoot and a hold time of 37ms at 120/230Vac input.
