Simple temperature measurements with Temperature Sensor included in the Unit.
High-precision Measurements.
Measurement of generated power (regenerative power),
leading reactive power, lagging reactive power, and consumed power.
Power measurements on the primary side of inverters,
which are widely used to save energy.
Automatic range switching for accurate measurement of standby and stopped power K2CM-4H Communications Manual.
Energy-saving Functions.
Conversion to monetary cost. (Also used for classified standby and stopped power.)
Alarm outputs can be selected for active power, reactive power,
regenerative power, current, voltage, or power factor.
The Power Monitor can log measurement data and supports Modbus communications.
Installation and Settings.
Direct measurement of three-phase, four-wire, 400-V line voltage.
Simple measurements without voltage wiring.
Incorrect voltage wiring detection. Time specification: Instantaneous type.
Current setting range: 2 to 8 A.
Operating voltage: 200/220/240 VAC.
Resetting method: Manual.
Solid-state Relay Enables Choice of Three.
Operating Functions (Overcurrent, Open,
phase, and Reverse-phase).
Protects 3-phase induction motors and their loads from damage.
Selection and combination of operating functions from overcur,
rent, open-phase, and reverse-phase.
Circuit and output relay operation can be checked by just operat,
ing the test button.
The set time value can be checked easily because operation time,
is indiccated from the start of operation K2CM-4H Manual.
Space-saving, integrated construction.
Note: If the K2CM is used with an inverter, the operating conditions will,
depend on the load wiring length, inverter carrier frequency, basic,
frequency, and load conditions K2CM-4H Manual. Error will occur in the operating,
values of the overload elements. It is recommended to test operation,
before using the K2CM.
