All parameters NOT specially mentioned are measured at 24,48,110VDC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

Fuse specifications of each model are shown as below. Type Fuse Type Reference and Rating B Fast Littelfuse 257, 30A, 32V C Time-Lag Conquer UDA-A, 16A, 250V D Time-Lag Conquer UDA-A, 8A, 250V Input Reverse Polarity Protection There is a MOSFET connected in series to the negative input line. If the input polarity is connected reversely, the MOSFET opens and there will be no output to protect the unit. Input Under-voltage Protection If input voltage drops to Vi min. -3V, the internal control IC shunts down and there is no output voltage. Hold-up Time D type is in compliance with S2 level, while B and C types are in compliance with S1 level at full load output condition. To fulfil the requirements of S2 level, B and C types require de-rating their output load to 70%, please refer to the curve diagrams below.
