About This Product

■Summary

In recent years, the introduction of digital switchboards has been expanding, but when conducting sequence tests, the steady voltage, that is, the bus voltage of 110V (between lines) is required. It is necessary to apply a single-phase AC voltage of 63.5V or 110V synchronized with the bus voltage as the three-phase AC voltage and line voltage. Conventionally, in order to obtain this steady voltage, three-phase distortionless testers, etc. was used, but it is large in size and weight, requires adjustment because it is a general-purpose device, and is expensive. This steady-state voltage generator was developed through research commissioned by Tohoku Electric Power Co., Inc.'s Morioka Technology Center in 2006 in order to easily obtain steady-state voltage.

■Compared to conventional testing machines, the output is smaller at 20 VA, but it has the following features.

・Uses commercial power supply (AC100V) ・Small and lightweight ・Easy to handle (no adjustment required as it is a dedicated device) ・Low price (approximately 1/10 or less of conventional equipment)
