The LTH Series is Low Frequency type On Line UPS, also known as Transformer type On Line UPS (Industrial On Line UPS).

The LTH Series provides reliable and stable pure sine wave output power for your critical loads. With advanced technology of Rectifier, IGBT, PWM and CPU control, the LTH Series is highly reliable. Besides, the LTH Series applied true galvanic isolation design to solve the problem of Utility such as noise, lighting, leakage current etc. Furthermore, the LTH Series has individual inverter transformer at output which supports per phase to endure 100% unbalance load.

With its outstanding features, the LTH Series provides safe, reliable and uninterrupted power to your critical electronic equipments at all times.
