El Monte, CA, August 2005 — AMREL/AMERICAN RELIANCE, INC. announced today the release of their new SPS and HPS Series of Programmable Switching Power Supplies. This expansion of AMREL’s ePower line of Power Supplies will offer customers more choices and more control. AMREL anticipates their extensive catalog of products will provide customers with an unparalleled choice of power supplies. The ePower’s SPS rack-mount units range from 1.2 to 30kW, up to 800Vdc, and 2700Adc. The HPS panel-mount units range from 20 to 900kW+, 10 to 2500Vdc, and 23 to 7500Adc. Both units are available with an embedded Ethernet interface. Allowing engineers the choice of Ethernet capabilities provides them with the opportunity to increase and expand on their testing capabilities and high speed wireless communication demands. AMREL exceeds customer’s requirements, whether it is a GPIB interface which requires only one address for the entire system or the built-in output isolation and polarity reversal relays available with AMREL’s 1.2kW SPS models. AMREL’s SPS and HPS Series include models capable of being configured to act as either master and/or slave. Network control options available via Ethernet or RS-485 include the MC-2 and MCU-2. The MCU-2 allows the slave units to be connected in a star configuration via the Ethernet Bus. AMREL’s technology has enabled these power supplies to have a wide selection of interface options, including front panel control, external (0–10V) analog control, and Ethernet/USB. The user-friendly front panel contributes to the ease of programming. They are built to offer outstanding programming with exceptional resolution and accuracy. The ePower SPS and HPS units offer precise line/load regulation in addition to low peak-to-peak ripple-noise. With the ability to control up to 31 individual slave units through one master unit, managing multiple outputs through one controller enables users a greater range of flexibility and more efficient transmission of data.The SPS series offers GPIB/SCPI, RS-232, Ethernet & USB interfaces, closed-case calibration, 10-turn Potentiometer for voltage and current control, programmable protection modes, master/slave capabilities, and full function keypad control with auto-sequencing and triggering. The HPS series offers high dielectric voltage tolerance, closed-case calibration, certified LabWindows/CVI and LabVIEW for GPIB, Serial, TCP/IP communications, high efficiency and high power factor (<0.9 PF) operation. AMREL also offers the NEMA 3R weather enclosure for harsh environment storage options. Both the ePower SPS and HPS Series have the design flexibility to customize and/or modify to meet customers special system requirements.AMREL/AMERICAN RELIANCE, INC. is responsible for designing, developing and manufacturing high quality programmable power supplies and electronic loads.
