TDK-Lambda’s VEGA

450W – 900W Modular DC Power Solution

TDK-Lambda’s Vega series of 450W, 650W and 900W modular supplies are fully configurable and can provide between one and ten adjustable outputs. Up to 5 modules – single or dual outputs – can be fitted with output voltages from 1.8V to 64V and output currents of up to 120 amps. No minimum loads are required and inhibit, AC fail, current-share and DC-good signals are available as options. Both IEC 60950-1 and medical 60601-1 certifications are available with a variety of cooling and earth leakage current options.
