ESU-1201-220 intelligent energy saving switch can support TEMIC E5551/E5557 RF cards. Only these two cards or compatible RF card can get power. ESU-1201-220 can cooperate with TalenCa Temic Lock system to save power sufficiently in hotels.
The power supply of ESU-1201-220 is AC220V. ESU-1201-220 can connect to AC220V city electric power and control the output to devices directly. The maximum current that ESU-1201-220’s relay contact can afford is 20A/250VAC. Without controlling Air-conditioner, both of them can support the power consumption in hotel rooms. If bigger power consumption is needed, AC contactor can be equipped. ESU-1201-220 can control AC contactor, so AC contactor will then control the devices.
