Approvals and compliance

From the manufacturer's datasheet for this series

Eurasian Economic Union

  • EAC

    Conformity with the Eurasian Economic Union technical regulations, covering Russia, Belarus, Kazakhstan, Armenia and Kyrgyzstan. TP TC 004 is the low-voltage regulation and TP TC 020 the electromagnetic-compatibility one, so which number appears tells you what was assessed.

Isolation and electromagnetic compatibility
Withstand voltage 24Vin / 48Vin models: I/P-O/P 1.6KVDC, 110Vin models: 3KVDC
Isolation resistance I/P-O/P:1000M Ohms / 500VDC / 25℃/ 70% RH
EMC emission Parameter Standard Test Level / Note Class A/B with external components (see page 6~7)
