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.

QS10.121

Verified stock: 1

PULS QS10.121 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 15A at 12Vdc and 13.5A at 15Vdc, utilizing spring-clamp connections for connectivity. It supports a supply voltage range of 85Vac-264Vac for AC and 88Vdc-188Vdc for DC, with specific nominal values across a wide spectrum. The QS10.121, part of the Q-series, measures 60mm in width, 124mm in height, and 117mm in depth, housed in an aluminium casing. It is compatible with single-phase (1AC) or DC networks, delivering a rated power of 203W at 15V, 180W at 12V, and can momentarily supply up to 270W for 4 seconds. The output voltage is adjustable between 12Vdc and 15Vdc, featuring comprehensive protection functions including overvoltage and overload/short-circuit protection. The unit allows for series or parallel operation to increase output power and is designed to handle back-feeding loads without malfunctioning. Efficiency rates vary with input voltage, achieving up to 0.918 at 230Vac. It exhibits a peak current consumption of 10A, with a start-up delay between 340-800ms and a hold time of 32ms at nominal input conditions. Power dissipation stands at approximately 16.1W to 16.7W under full load conditions, and the electrical durability ranges significantly based on operating conditions, with up to 215000 hours at 25°C and 30A output with 1AC 230Vac input. The output stage capacitance is 7000µF, and ripple is maintained at 50mVpp across a 20Hz to 20MHz range.
