Energy Meter - 17675 ENERGY METER

SPECIFICATION DATA

FEATURES

Intelligent microprocessor logic. Large, high-contrast LCD display. Energy (kWh) reading backed up by non-volatile memory. Keyboard-selectable reading. Keyboard-programmable CT ratios. Counter reset and set-up disable feature. RMS measurement to the 16
th harmonic. Class-2 accuracy according to IEC1036 standard.

SPECIFICATION DATA

Current input 16 A direct and/or 5 A external secondary current transformers Voltage input 200...240 V 50/60 Hz (single phase); 200...240 V 50/60 Hz, 4-wire star configuration (three- phase)

GENERAL

Display High-contrast, 7-mm, 8-digit alphanumeric LCD display The EE7003A1008 3-Phase Power and Energy Meter is suitable for energy cost allocation tasks in the field of building automation, in office buildings, residential complexes, shopping centers, camp sites, etc. equipped with single-phase or three-phase power systems. Readings are RMS (root mean square) values measured by a digital circuit guaranteeing maximum precision, reliability, and stability over time. Automatic internal scale shifting guarantees Class 2 measurement accuracy in accordance with IEC1036 standards. The non-volatile energy data memory retains data even when disconnected from the power supply for long periods. Automatic amplifier offset correction prevents accuracy drifting in ambient temperatures and over time. The unit is calibrated and tested using an automated digital calibration system. The unit is designed to measure readings on unbalanced 4-wire star-configuration networks. The unit is fully keyboard- programmable. When setting the current inputs, you can choose from among twenty-nine possible CT (current transformer) ratios. The unit is self-powered from the voltage inputs. The EE7003A1008 reference standard is IEC1010 Accuracy Class 2 according to IEC1036 standard Data retention Static non-volatile EEPROM memory (no battery required) Crest factor 1.7 on voltage & current inputs Consumption 3 VA CT burden 0.5 VA Temperature range 0...+50 °C Relative humidity Max. 90%, non-condensing Inputs Voltage: 250 V at 20...800 Hz current: 5 A at 20...800 Hz Input overload Voltage: max. 264 V
