Towo inverters Test Feedback Grid Simulator, Towo TPV7000 Feedback Grid Simulator - Simulated Grid Power Supply Bidirectional AC Power TPV7000

　　Product Features:

　　Three-phase voltage independently adjustable, each phase voltage 0-320V; with three-phase phase angle adjustable from 0-359°.

　　■ Editable up to any harmonic 1-49, including common harmonics in laboratories

　　■ Active PFC capable, with low voltage and zero voltage ride-through tests available

　　■ Can perform over/under voltage, over/under frequency tests; set the required voltage or frequency changes on the programmable panel, and after running, each change in voltage or frequency will trigger a level. It is very accurate and convenient for this experiment.

　　■ Output frequency 45.000-99.999Hz, with variable 0.001 Hz/10ms, easily adaptable for under-frequency experiments, islanded prevention test

　　■ Two modes: LIST and STEP, allowing for 30 different voltage, frequency, and time settings, and capable of continuous cyclic testing. Operating time can be set as short as 10ms, suitable for simulating grid tests, achieving gradual voltage and frequency changes, step function, and easily completing low-voltage penetration tests.

　　Suitable for islanding prevention tests

　　Provide embedded intelligent PC-based monitoring system

　　Output Current, Voltage Limit Function

　　■ It features both DC and AC outputs, with the DC voltage being non-adjustable at a fixed 300V (single-phase input) and 500V (three-phase input).

　　High measurement accuracy, applicable to testing sine half-wave currents and similar waveforms with DC components

　　■ Utilizes Direct Digital Synthesizer (DDS) waveform generation technology, featuring high frequency stability and excellent continuity.

　　■ Features 9 memory groups, allowing common parameters (voltage V, frequency F) to be stored for easy recall during use.

　　■Choose from communication interfaces such as RS232C, RS485, and GPIB.

　　■ Protection Modes: Overvoltage, Overcurrent, Overload, Short Circuit, Current Limiting, Voltage Limiting, etc.

　　■Offer readings for Root Mean Square (RMS) voltage, RMS current, active power, frequency, power factor, peak current, etc.

　　■ Overload-resistant, with reaction time under 2ms, and the instant current can withstand three times the rated current.

　　Voltage, frequency, and time can be digitally input via buttons; high resolution, 320×240 LCD display.

　　■ Customizable grid simulators in various specifications to meet customer requirements

　　Meets Standards:
