| TDK Corporation (TSE 6762) announces the introduction of the 3000 watt TDK-Lambda brand HWS3000 programmable AC-DC power supplies in a 270 x 150 x 61mm case size. The nominal output voltages (24V, 48V, 60V or 130V) and output currents are fully programmable (CV/CC) from zero up to their maximum rating. The HWS3000 series is available with an 85 – 265Vac single-phase or three-phase 170 – 265Vac input.
Output programming can be achieved using a serial RS485 interface (MODBus protocol) or analog 1 – 5V or 4 – 20mA signals. These very compact products also feature a variable speed fan with typically 45dB audible noise at <70% load, and a 25oC ambient temperature. The power supplies can be used in a wide range of applications, including test and measurement, semiconductor fabrication, RF amplifiers, laser machining, printing, and industrial equipment. The HWS3000G can deliver 1500W with a low-line single-phase input voltage (85 to 132Vac) and 3000W at high-line (170 to 265Vac). The HWS3000GT provides 3000 watts from a three-phase input voltage of 170 – 265Vac. Four nominal output voltages, 24V, 48V, 60V and 130V, can be programmed to provide 0 – 28.8V, 0 – 52.8V, 0 – 66V, and 0 – 156V. Up to three units can be connected in series, or ten units in parallel. The output voltage slew rate can be digitally programmed and monitored, along with information regarding cumulative operating time, fault log, and product identification information. Digital programming can be performed without turning the power supply on. A 5V 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 reduced, allowing reliable operation in the compact package size. The HWS3000 models can operate in -20oC (-40oC start-up) and up to +70oC ambient temperatures, derating linearly from 50oC to 50% load at +70oC. Both models have a five-year warranty and conservatively rated electrolytic capacitor temperatures for long field life. The output terminals are user-configurable for horizontal or vertical connections. The input to output isolation is 3000Vac, input to ground 2000Vac, and output to ground 1500Vac. The leakage current is <0.85mA and the maximum operating, transportation and storage altitude is 5000m (2000m for the IEC/EN62477-1 standard). 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.
