Variable Voltage Transformer

Introduction

Variable voltage transformers are very convenient and useful where different voltages are required to conduct tests or inspections. Examples are instrument calibration labs, QC department in the manufacturing sector, etc. They are also suitable for use as step-up or step-down transformers in areas where supply voltage is too low or too high.

We are the first local manufacturer of variable voltage transformers in Malaysia under the company’s brand QPS. QPS has catered a range of single phase from 5 to 60 Ampere and three phase from 5 to 30 Ampere variable voltage transformers to suit different customers’ needs.

QPS variable voltage transformer uses high quality materials and stringent quality controls to ensure that only high quality products are produced at all times. QPS variable voltage transformer provides more than just quality, reliability and compatibility. It also provides strong technical supports to our valuable customers.
