▶ The input terminal is completely isolated ”circuit breakers”, so that effective on the input terminal of the transformer (electric the power supply voltage supplied by the network) has played a role of a good filter. Thus to the electrical equipment provides pure power voltage.
▶ Maintenance-free, easy to install, low comprehensive operating cost.
▶ Low loss, small noise, heat dissipation ability.
▶ According to customer demand, configurable enclosure and safe.
