Puls

Product Lifecycle: Active

PULS QS20.481 is a power supply unit designed for AC/DC conversion with a 50% power reserve. It features DIN rail mounting and operates within an ambient air temperature range of -25 to +70°C. The unit is equipped with a DC-OK relay contact output and offers a rated current of 10A at 48Vdc and 8.7A at 55Vdc, with a power derating from 12W at +60°C to +70°C. Connection is facilitated through spring-clamp connections. The supply voltage ranges from 85Vac to 264Vac for AC input and 88Vdc to 188Vdc for DC input, supporting various nominal voltages and featuring specific turn-on and shutdown voltages. Housed in an aluminium casing, it is suitable for single-phase (1AC) or DC networks, with dimensions of W82mm x H124mm x D127mm. The rated power is 480W, with a short-term capacity of 720W for up to 4 seconds. Output voltage is adjustable between 48Vdc and 55Vdc. Protection functions include output overvoltage protection and overload/short-circuit protection, with capabilities for series or parallel operation for increased output power. Efficiency rates vary with input voltage, and the unit exhibits specific current consumption, time delay, hold time, power dissipation/losses, and electrical durability metrics. Ripple is maintained at 100mVpp, and the output stage capacitance is 3100 µF.

CP10.241-C1

CP10.241-C1

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.
