Measured with noise probe directly across output terminals of the power supply. Hold-Up Time 15 ms minimum from loss of ac input at full load, nominal Transient Response line (115 Vac). 500 µs typical response time for return to within 0.5% of final value for a 50% load step change. Δi/Δt<0.2 A/µs. Output Power Maximum voltage deviation is 3.5%. Startup/shutdown 50 W continuous, 60 W peak. Peak ratings are for 60 s overshoot less than 3%. maximum duration, 10% duty cycle. During peak load condition, output regulation may exceed total regulation Voltage Adjustment limits. Built-in potentiometer adjusts V1 ±5%. Output Regulation EMI/EMC Compliance To maintain specified regulation on multi-output models, All models include built-in EMI filtering to meet the output #1 load power must be at least 1/5th of, and not following emissions requirements: greater than 5 times output #2 load power.

Medical Safety Input Protection All GLM models are approved to UL2601, CSA22.2 No. Internal ac fuse provided. Designed to blow only if a 601, IEC601-1 and EN60601-1. catastrophic failure occurs in the unit—fuse does not blow on overload or short circuit. Inrush Current Inrush is limited by internal thermistors. Inrush at 240 Vac, averaged over the first ac half-cycle under cold start conditions will not exceed 37 A. Condor D.C.
