In addition to EN60950 and CE approvals, standard features include a line/load regulation of less than 0.5%, input/output isolation of 3 kVdc, leakage current of less than 0.7 mA, and a 20-ms hold-up time. Each unit comes with output-overload, over-voltage, and short-circuit protection. Output is adjustable by ±10% and MTBF per MIL HDBK 217F is greater than 100,000 hours. All models in the family operate over a temperature range of -10°C to +50°C with no derating or heat sinking with cooling via free-air convection. Pricing is under $25 each in OEM quantities.
