Simple-to-customise Behlman AC power sources from PowerstaxPowerstax is the UK distributor for Behlman Electronics Inc., known for its leadership in providing power products for industrial and commercial applications as well as military shipboard, airborne and mobile systems.

An options list is now available illustrating how their 15 BL High-Power Series AC Power Sources/Frequency Converters can be selectively customised in many ways, without the typically high cost of engineering a bespoke power supply.

According to Tim Worley, CEO of Powerstax: “Since a recent cost reduction of the Behlman BL High-Power Series AC Power Sources, the demand for a number of options became more evident. The V and F options, for fixed output voltage and fixed output frequency, became so popular that their cost was also reduced. A chart showing 13 options is now available on each of the BL Series specification sheets to help engineers customise these power sources to better meet their needs.”

Behlman’s BL High-Power Series AC Power Sources supply clean, regulated AC power in a compact design at competitive prices. The BL High-Power Series with Options V and F are available with either single- or three-phase output in a wide range of power, from 1KVA to 20KVA. Inputs are any worldwide three-phase mains power with some models available with single-phase input. The BL High-Power Series delivers all the quality features our customers have come to expect from Behlman: clean sine wave output with excellent line and load regulation, high efficiency, and low harmonic distortion. A multi-pulse input transformer offers low-input harmonic distortion and high power factor as required by MIL-STD-1399. Unique protection circuitry provides over-temperature and short-circuit protection, as well as voltage fold-back during overloads, to maintain undistorted waveforms. Line drop compensation, phase angle adjust, output on/off, and 0-10V analogue control come standard.

Options include remote interfaces (RS-232 or IEEE-488) for setting and monitoring a motor test option that has the capability to soft-start motors, pumps and compressors, thereby eliminating the need for higher-power devices.

Small size, quiet operation, and high efficiency make the BL High-Power Series with options V and F well suited for industrial product testing, precision avionic test and power conversion, ATE, bulk power, and motor generator replacement. Other models are available with variable voltage and frequency, using ten-turn potentiometers or remote interfaces (Analog, RS-232 or IEEE-488).

Powerstax designs and manufactures an extensive range of standard, value-added and custom AC and DC power products for a broad range of fixed and mobile applications including hot-swap front-end AC-DC bulk power, DC-DC converter bricks and modules and programmable, modular, rack mounted power supplies.

Drake range of transformer rectifiers from Powerstax offers output currents to 5000A and output power up to 1000kVA and beyond. Power products are available for harsh (marine, offshore, desert) and hazardous (Zone 1 and Zone 2) environments and can be oil, air or water cooled and can be sealed up to IP65 if the environment dictates with purge and pressure systems and heat exchangers incorporated if required.

The main markets served by Powerstax include high-end industrial, defence, vehicle and transportation, defence and avionics, impressed current cathodic protection, water treatment, test, measurement and control and medical equipment. For more information visit
