Product Overview

Features:

■ three-phase voltage independently adjustable, each phase voltage 0-320V; a three-phase phase 0-359 ° adjustable
■ having to edit any harmonic 1-49 times, containing laboratory common harmonic
■ with active PFC, do LVRT and zero voltage ride through experiments
■ can be done / undervoltage, over / under frequency test; programmable panel set up required change in voltage or frequency, running, voltage or frequency
  Every change triggers a level, in doing this experiment, very accurate and convenient
■ Output frequency 45.000-99.999Hz, with a 0.001 Hz / 10ms variable, can be easily done under frequency precision experiments, anti-islanding test
■ LIST, STEP two models, perform 30 different sets of voltage, frequency, time setting, and for a continuous cycle test. The shortest running time
  To set 10ms, it can be used to simulate the grid test for voltage, frequency gradients, step-order functions, easily complete LVRT test
■ can do with anti-islanding test
■ provides embedded PC intelligent monitoring system
■ output current, voltage limit function
■ DC and AC output having two parts, of which the DC voltage is not adjustable to a fixed 300V (single-phase input) and 500V (three-phase input) of two
■ high accuracy, test applies a current half-sine and similar various waveforms with DC component
■ The use of advanced direct digital frequency synthesizer (DDS) waveform generation technology, high frequency stability, good continuity;
■ has 9 sets of memory, can be frequently used parameters (voltage V, the frequency F) storage for easy call when using;
■ with RS232C, RS485, GPIB communication interfaces to choose from;
■ protection mode: overvoltage, overcurrent, overload, short circuit, current limiting, limit pressure and the like;
■ provide rms voltage, rms current, active power, frequency, power factor, peak current, reading;
■ In addition to the 100 percent load load, response time is less than 2ms, strong overload capability, instantaneous current can withstand 3 times the rated current;
■ voltage, frequency, time digital key input, high accuracy, 320 × 240 LCD display.
