Dimensions:
The GCU500 is packaged in a 3.3" x 6.5" x 1.55" package and achieves EN55011/32
Level B conducted emissions compliance whilst maintaining very low earth leakage
currents, making it suitable for a wide range of 1U and other industrial, IT and medical
applications.
GCU500:
3.30 x 6.50 x 1.55” (83.8 x 165.1 x 39.3 mm)
GCU500-EF:
3.30 x 8.24 x 1.64” (83.8 x 209.3 x 41.7 mm)
The series has single output versions from 12 V to 48 VDC, dual-fusing for compliance with
IEC60601-1 and features minimal waste heat as efficiencies reach 93%. The GCU500 delivers up to 500 W of power over an operating range of
-40 °C to +70 °C and offers remote on/off control and power fail signal along with 5 V standby and fan supplies.
