Top Notes 1. High active (or open) in On/Off control pin. Low logic level (0~0.9V) will disable the converter. 2. Once the protection circuit performs, the converter will shutdown. One should remove the fault and re-power again (not auto-recover) No. Model Input Output Iomin Iomax Load Reg. Power 1. QMT100-24-3.3 18-36 VDC +3.30VDC 0.00A 30.00A ±0.50% 99.00(w) 2.
