Single-Output AC-DC Power Supplies


Announced by Acopian, is the expansion of its 1U AC-DC programmable power supply portfolio to include an extensive family of 450W 1U programmable single-output AC-DC power supplies.  Offered in rack and benchtop models, the new power supplies are notably available in 135 different voltage ratings spanning from 1 Vdc to 135 Vdc and feature current ratings up to 40 A. The high efficiency, high-density 450W family is specifically engineered to satisfy the requirements of a broad array of OEM, industrial and laboratory applications including automated test equipment (ATE), water purification, electro plating, product development, industrial controls, motor controls and cathodic protection.    

The power supplies accommodate the universal AC input voltage of 95 to 265VAC, 49-420Hz with active power factor correction (PFC) of 0.99 to ensure operation in challenging AC environments and compliance with European EMC requirements. For added support, units are configurable with an optional fixed auxiliary output of between 3.3Vdc and 125Vdc, up to 180W.  A comprehensive and intuitive front panel supports reliable linear controls for precise adjustment, and optional digital LED voltage and current meters.  

Voltage and current monitor outputs, and provisions for N+1 redundancy and paralleling for higher current, are also optionally available.  Pluggable connectors facilitate quick and easy wiring of control and input leads.  Common to all models within Acopian's latest family of 450W 1U programmable single-output AC-DC power supplies are PFC, universal input, built-in over voltage protection (OVP), and constant current control to provide further flexibility.  Standard features additionally include short circuit and overload protection, "soft start" and "no load" operation, internal EMI filtering, thermal protection, remote sensing and RFI shielding. Moreover, all models can operate in a constant-current or constant-voltage mode.  Digital interfaces, including RS232, RS485, Ethernet and USB, are available upon request.
