Frequency meter power meter T203PM300-MU

multimeterenergy meterwith power quality and harmonic analyzer

Single-phase power meter with direct current and energy measurement up to 300 A T203PM300-MU is a single-phase AC/DC TRMS network analyzer with ModBUS interface, analog and digital output, and inputs with current measurement ranges up to 300 A and voltage 290 Vac, 1000 Vdc. The instrument performs direct measurement of current and energy without using external CTs. T203PM300-MU measures values of voltage, AC/DC current, active/reactive/apparent power, power factor, frequency, and harmonic distortion (THD), and transmits them on an analog or digital output. The T203PM models have analysis capability up to the 21st harmonic and are equipped with a digital contact that can be used as an alarm or counter. The configuration is made through EASY SETUP 2 software and a Micro USB programming port. T203PM power meters are particularly robust as they have a wide operating temperature range, -25..+65°C, insulation up to 3 kVac (on bare conductors), and safety class CAT. III 600V (bare conductor) and 1kV (insulated conductor). The devices can be mounted on IEC EN60715 35mm DIN-rail, using wall plugs, or suspended using cable ties. In combination with devices such as Z-KEY/R-KEY gateways, they can be easily integrated into Ethernet networks and complex systems.
