S1004F-однофазный счетчик электроэнергии тест скамейки

S1004F-A single phase energy meter test bench 1. Brief Introduction: KP-S1004F-A single phase energy auto-calibration system is a new generation, high precision energy meter calibration equipment. It uses the advanced technology and electronic components available in 90 decade . The test bench can be operated from embedded keyboard or operated from PC software. 2. Advantages: v. DDS technology signal generator: The signal generator adopts digital sine wave composing technology. The signal generator can trace the voltage phase and supply a dummy load to the tested meter by outputting adjustable current with different phase; w. High efficiency D-Class current amplifier and voltage amplifier: The equipment use PWM power amplifier(or we called D-Class amplifier), which is high efficiency (>85%) and very low heat consumption. The amplifier has protection circuit itself, it can avoid damage due to wrong connection or other manual operations. Current amplifier and shifter can output any current from 0.001A to 100A; Voltage amplifier can output any voltage from 100V to 300V; x. DCS framework designed error calculator system. The error calculator system is designed as DCS framework, every meter position has one isolated error calculator, error data is transferred from RS485 Bus, PC can receive every meter’s error data and then displayed it on the screen, the error calculator can receive signal which due to TTL / OC or Optical head output. y. Can be controlled from keyboard or software. The equipment has operated keyboard itself, the equipment can be operated form software and also it can be operated from keyboard. Without PC you can also test meter’s error. 3.
