XP Power has introduced the HDL3000-HV series of single-phase input 3kW AC/DC power supplies with output voltages from 150V to 400VDC, with up to 800VDC achieved by connecting units in series. All models provide output voltage and current adjustment ranging from 0% to 105% utilising analogue (by voltage or resistance) or digital (I2C, RS485 and RS232) interfaces allowing the user to optimise and tailor the power solution to the application.
The series, with both constant voltage and constant current operation, satisfies applications that need higher supply voltages such as battery test and simulation systems, test and burn-in equipment, laser systems, electrolysis, LED curing, lighting and heating, motor drives and cathodic protection.
Five output voltage versions are offered comprising 150V, 200V, 250V, 300V and 400V, each with a 5V/0.5A or 9V/0.3A user-selectable standby output. The output can be trimmed within ±5% as well as the output programming function. For applications needing higher current, up to eight models can be joined in parallel with active current sharing and built-in ORing diodes simplifying interconnections.
Measuring 170mm x 64mm x 301.49mm, the compact units are cooled by forced airflow from the integrated, variable speed fan. Operating temperatures are between -20C and +60C with full power up to +50C, derating linearly to 50% load at +60C.
The series is safety certified to IEC/UL/EN 62368-1 for AV/ICT equipment. The units comply with EN 55032 Class A conducted and radiated emissions, and meet the EN 61000-3-2 harmonics and EN 61000-4-2 immunity standards. All models come with a three-year warranty.
