MULTI POWER MONITORING UNIT
(Clamp-on current sensor CLSE, Modbus)
Functions & Features
AUXILIARY POWER SUPPLY
AD4: universal
• Multi Power Monitoring Unit for Modbus.
• By using clamp-on current sensors, there is no need of
current transformers.
100 – 240 V AC (Operational range 85 – 264 V, 50 / 60 Hz) /
110 – 240 V DC (Operational range 99 – 264 V,
ripple 10 %p-p max)
• Up to 8 circuits can be measured. (Common voltage
measurement)
• Current sensors are easy to install in existing systems.
Wide input range of 5 to 600 A is availabe.
• All measured values, counter values, display mode,
setting data are stored in the non-volatile memory when
power is off.
