Programmable 1U 750-W AC-DC power supply family offers wide-adjust output voltages

February 06, 2013 // By Paul Buckley
Acopian has introduced a new family of programmable AC-DC power supplies which feature wide-adjust output voltages from 0 V to 5 V to 0 to 135 V and current capabilities up to 70 A.

The 1U format single output voltage power supplies offer 750 W of output power.  

The rack and benchtop modules notably provide high power density, low ripple and a user-friendly front panel.

 Acopian's programmable switching power supplies with wide-adjust output voltages are suitable for use in a broad range of ATE, OEM and laboratory applications such as component testing, semiconductor burn-in, test and measurement, RF Amplifiers, LED/laser testing, as well as a variety of electromagnetic and electromechanical applications.

The power supplies accommodate the universal AC input voltage of 95 to 265 VAC, 50/60 Hz with active power factor correction (PFC) of 0.99 single phase to ensure operation in challenging AC environments and compliance with European EMC requirements.  For added support, models can be configured with an optional fixed auxiliary output of between 3.3 Vdc and 125 Vdc, up to 180 W.

An 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 are provided to facilitate quick and easy wiring of control and input leads.

All models within Acopian's latest family of programmable AC-DC power supplies are provided standard with active PFC, universal input, constant current, built-in over voltage protection (OVP), and constant current control to provide further flexibility.  Additional standard features include ‘soft start’ and ‘no load’ operation, short circuit and overload protection, thermal protection, internal EMI filtering, RFI shielding, and remote sensing.

Digital interfaces, including RS232, RS485, Ethernet and USB, are available upon request.


While firm pricing is determined according to customers' specifications, prices for Acopian's rack mounted 1U 750W programmable AC-DC power supplies featuring wide-adjust output voltages start at $835.00 per unit.  Benchtop unit pricing starts at $845.00 each. Modules are shipped within three days.
