MEAN WELL PSPA-1000-48 Switching Power Supply 48V DC 1.008 kW 21A Chassis Mount Remote Control Functions High Efficiency

The MEAN WELL PSPA-1000-48 Switching Power Supply is engineered to deliver dependable performance for industrial, communications, and network equipment, with a 48V DC output at 21A and a total output power of 1.008 kW. It is well-suited for applications requiring high current and stable voltage regulation, such as electric motor drives, control systems, and advanced electronics.

This model features a chassis mount enclosed design that simplifies installation and maintenance, and offers robust physical protection for demanding environments. With a wide operating temperature range from -20°C to +70°C, the PSPA-1000-48 ensures reliable operation even under challenging thermal conditions.

Efficiency is a key specification, with rated performance up to 94%. The power supply incorporates active power factor correction (PFC), enhancing energy conversion and reducing input current distortion. Forced air cooling is delivered by a built-in DC fan, ensuring that power output remains stable, while comprehensive protection mechanisms guard against short circuit, overload, over voltage, and over temperature situations.

Several remote control functions are available, including remote ON/OFF, remote sense, and DC OK signal monitoring, facilitating integration into advanced automated systems and allowing for sophisticated system diagnostics. The device also supports current sharing for parallel operation up to 4000W, making it a flexible solution for scalable power systems.

Input compatibility covers a full range - 90 to 264V AC and maximum input at 370V/264V DC. The PSPA-1000-48 is constructed with industrial-grade standards, carrying approvals including UL 62368-1, TUV BS EN/EN 62368-1, IS 13252(Part1)/IEC 60950-1, EAC TP TC 00, CSA C22.2 No. 62368-1, CCCGB4943.1, BSMI CNS143361, and AS/NZS62368.1. It is designed for environments where safety and reliability are paramount.

The compact physical dimensions (170 x 120 x 93 mm) and a weight of 1.9 kg allow for integration into constrained spaces while maintaining the ability to replace lower wattage PSP-600 units without modifying panel space, streamlining upgrades for system designers.

Main industrial use cases include process automation, control panel power supplies, high-bandwidth communications, and large-scale industrial electronics. Explore more Switching Power Supplies from MEAN WELL in the Electronics & Electricals category at EnvMart.
