AC/DC power supply with a wide three-phase input range

With the HWS3000GT4, engineers achieve greater installation flexibility, improved compatibility with global industrial power supply systems, and higher reliability in environments with demanding electrical requirements.
The nominal output voltages and currents are fully programmable from zero up to their maximum rated values in constant-voltage (CV) and constant-current (CC) modes, enabling precise control and rapid system integration in a wide range of industrial applications.

Analog and Digital Programming

Output programming can be achieved using a serial RS485 interface (MODBus protocol) or analog 1 to 5 V or 4 to 20 mA signals, enabling straightforward connection to PLCs, automation systems, and test equipment. These very compact products also feature a variable speed fan with 45 dB audible noise of less than 70 percent load, and a 25 ºC typical ambient temperature. The HWS3000 series can be used in a wide range of applications, including test and measurement, semiconductor fabrication, RF amplifiers, laser machining, printing, and industrial equipment. The HWS3000GT4 model provides 3000 W from a three-phase input voltage of 340 to 528 VAC. Six nominal output voltages, 24 V, 48 V, 60 V, 80 V, 130 V, and 250 V, can be programmed to cover voltages from 0 to 300 V.
Available in a compact 270 x 150 x 61 mm case size, up to three units can be connected in series or up to ten in parallel, offering scalable solutions for higher voltage or current requirements. The digitally programmable voltage slew rate, along with monitoring functions such as cumulative operating time, fault logs, and product identification, enhances system control and diagnostics. Notably, digital programming can be performed without powering the unit, improving safety and setup efficiency.

Wide operating temperature range

A 5 V, 2 A standby voltage, remote on/off, remote sense, fan fail, and power good signals are fitted as standard. With efficiencies of up to 93 percent, internal heating is minimized, allowing reliable operation in the compact package size. The HWS3000 models can operate at ambient temperatures ranging from -20 ºC (-40 ºC start-up) to +70 ºC, derating linearly from 50 ºC to 50 percent load at +70 ºC. A seven-year warranty in the Americas and EMEA regions and conservatively-rated electrolytic capacitor temperatures further support to long-term reliability.
