MR504E Wattmeter Vocational Training Equipment University Educational Equipment Transformer Training workbench I.Product Overview 1.1 Overview The Wattmeter/VAR Meter Module is one of the metering modules designed for electromechanical (EMS) systems. It features a Wattmeter and a VAR meter designed to directly measure active and reactive power in a balanced three-phase circuit. Each meter has a zero-centered cable scale to show the direction of power flow. Its electronic design uses voltage and current sensors to sample the line voltage and current. The voltage and current circuits are internally connected so students only need to connect the "Line" and "Load" terminals of the module. 1.2 Features 1. The product has excellent electrical safety performance. 2. The product design is beautiful and simple in structure. 3. The product adopts anti-corrosion measures and solid materials, which are strong and durable, greatly extending the service life of the product. II.Performance Parameter 2.1 Technical Parameters Power supply parameters: three-phase AC 220V Wattmeter range: 300-0.300W Voltmeter range: 300-0-300 var Maximum voltage: 240V Maximum current: 1.5A AC power input: 24V Accuracy: 2% Instrument type: panel type 100 mm (4 inches) Movement type: d'Arsonval 2.2 Dimensions and Weight Dimensions: 154mm x 287mm x 440mm Weight: 3.9kg III.Components List and Detailed Introduction 3.1 Main Part Number Name 1 Transparent baffle 2 Power transmitter 3 Power meter 4 Voltmeter 5 Terminal block IV.
