4; Explanation of Functions and Precautions 4-1, Input Voltage Range Input voltage range is single phase 85 ~ 264VAC (47~63Hz) Ps. can withstand 300VAC surge for 5 seconds during operation. Input voltage which is out of specification may cause unit Oscilloscope Bandwidth : MHz damage. For cases where conformance to various safety specs 300mm (UL, CSA, EN) are required, input voltage range will be 100 C1: 47uF Electrolytic Capacitor ~ 240VAC (50/60Hz). €2: Buff Film Capacitor 4-2.

8.1. Power supply mounting on DIN RAIL (1835 oF equivalent) (3) Press against the bottom front side for locking. Make sure input and output wire disconnected when Shake the unit slightly to check the locking action. mount power supply onto rail {1} Tilt the unit slightly rearwards, fit the unit over top hat rail. (4) In order to tighten the unit mounting, the Din tail stopper attached on both sides of the unit is recon mended. 8.2.
