Safety ConsiderationFor safety-agency approval system which power module used, power module must installed compliance with spacing separation requirements end-use safety agency standard, i.e., 1950, C22.2 950-95. input source non-SELV (ELV hazardous voltage greater than less than equal Vdc), module's output considered meeting requirements safety extra-low voltage (SELV), following must true:

Note: Take measurements module terminals. When socketing, place Kelvin connections module terminals avoid measurement errors socket contact resistance.
Design ConsiderationInput Source Impedance
power module should connected low-acimpedance input source. Source impedances greater than affect stability power module. When source impedance exceeds mount electrolytic capacitor (ESR kHz) close module input pins. This also recommended minimize reflected-ripple current well conducted radiated electromagnetic interference (EMI).

Feature DescriptionOutput Overvoltage Protection
output overvoltage clamp consists control circuitry, independent primary regulation loop, that monitors voltage output terminals. control loop clamp point that higher than point primary loop (see Feature Specifications table). This provides redundant voltage-control that reduces risk output overvoltage.

Either user-supplied switch override jumper should wired into circuit individual traces common with power current path. Connect switch jumper power module terminals (see Figure Configuring switch connection this prevents noise from falsely triggering remote on/off.
