Product description
Power supply for generating the 24 V control voltage in the control cabinet – for PLCs, contactor coils, valves, sensors and signaling devices. The transformer-rectifier design with smoothing capacitor is robust and insensitive to line disturbances.
The practical advantage of this version: using jumpers, it can be connected to either three-phase 380–420 V or single-phase 220–240 V – one unit covers both cases. Six connection variants are available (420 / 400 (415) / 380 V three-phase or 240 / 230 / 220 V single-phase); the jumper diagram is printed on the cover. Primary protection as printed: Siemens motor protection circuit breaker 3RV1011-1CA10 (2.0 A) at 400 V or 3RV1011-1EA10 (3.2 A) at 230 V. Output side 25 A gL/gG, external.
Key features: full 30 A up to 60 °C ambient – no derating in a warm control cabinet; smoothing capacitor mounted on the side of the cover; Phoenix Contact terminals on all three coils, output 31 (–) / 32 (+) plus PE, original terminals present; green “Power on” indicator on the cover for a quick visual check; CE, UL and CSA approvals – also suitable for machines destined for the North American market.
Tested by us and fully functional. Used part with the marks visible in the photos – scratches on the mounting plate, slight discoloration on the coils. Delivered exactly as pictured.
