TDK Corporation<\/a><\/strong> announces the expansion of the 3000 W TDK-Lambda HWS3000 programmable AC-DC power supply series with the introduction of the HWS3000GT4 model. Now available with a new wide-range 340 \u2013 528 Vac three-phase input option, this addition offers engineers greater installation flexibility, improved compatibility with global industrial power systems, and enhanced resilience in electrically demanding environments. The nominal output voltages and output currents remain fully programmable (CV\/CC) from zero up to their maximum ratings, enabling precise control and fast system integration across a wide range of industrial applications.<\/p>\n\n\n\n

Output programming can be achieved using a serial RS485 interface (MODBus protocol) or analog 1 – 5V or 4 – 20mA signals, enabling straightforward connection to PLCs, automation systems, and test equipment. These very compact products also feature a variable speed fan with 45dB audible noise at <70% load, and a 25\u00baC 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.<\/p>\n\n\n\n

The HWS3000GT4 model provides 3000W from a three-phase input voltage of 340 \u2013 528Vac. Six nominal output voltages, 24V, 48V, 60V, 80V, 130V, and 250V, can be programmed to cover voltages from 0 \u2013 300V. Available in a compact 270 x 150 x 61mm 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.<\/p>\n\n\n\n

A 5 V, 2A standby voltage, remote on\/off, remote sense, fan fail, and power good signals are fitted as standard. With efficiencies of up to 93%, internal heating is minimised, allowing reliable operation in the compact package size. The HWS3000 models can operate at ambient temperatures ranging from -20\u00baC (-40\u00baC start-up) to +70\u00baC, derating linearly from 50\u00baC to 50% load at +70\u00baC. A seven-year* warranty and conservatively-rated electrolytic capacitor temperatures further support long-term reliability. The output terminals can be configured for either horizontal or vertical connections, offering additional installation flexibility.<\/p>\n\n\n\n

Rugged versions of the HWS3000 are available with the \/HD option, which features dual\u2011sided board coating and is designed to withstand MIL\u2011STD\u2011810G shock and vibration requirements for harsh environments. Additionally, the \/RF option allows the airflow direction to be reversed to suit the needs of the end system.<\/p>\n\n\n\n

The series’ input to output isolation is 3000Vac, input to ground 2000Vac, and output to ground 1500Vac. The leakage current measures <0.85mA, and the maximum operating, transportation and storage altitude is 5000m (2000m for the IEC\/EN62477-1 standard).<\/p>\n\n\n\n

Safety certifications include IEC\/EN\/UL 62368-1 and IEC\/EN62477-1 (OVC III) with CE\/UKCA marking for the Low Voltage, EMC, and RoHS Directives. The units meet EN55032A, EN55011-A and FCC-A conducted and radiated emissions. The series also complies with the EN 61000-3-2 harmonics and IEC 61000-4 immunity standards.<\/p>\n\n\n\n
