EPS/UPS Used Isolation Transformer

The EPS/UPS Used Isolation Transformer is a supporting inverter transformer designed to improve power quality, safety, and stability in emergency power supply (EPS) and uninterruptible power supply (UPS) systems. By providing galvanic isolation between input (battery/mains/DC bus) and output (load), it helps prevent fault propagation, reduce electrical interference, suppress harmonics, and deliver more precise, stable voltage to critical loads. Built with high quality copper windings and cold rolled silicon steel sheets, it offers strong magnetic permeability, lower losses, and reliable continuous operation. Rated capacity is typically 1 kVA to 1000 kVA (customizable), with wide input/output voltage ranges from 1 V to 1000 V (customizable) and 50/60 Hz frequency options. The transformer supports single phase or three phase configurations, with insulation resistance typically ≥500 MΩ and insulation class options such as Class F or Class H (optional). It is designed for long unattended operation, with protection grades customizable (IP00/IP20) and an overload capability suitable for short duration high current (e.g., 2× rated current for 1 minute, project dependent). Typical electrical strength can be specified around 2500 VAC/1 min, with noise control (≤60 dB(A) within 1 meter) for indoor equipment rooms. Common applications include backup power supplies, emergency lighting for public facilities, data rooms, and other mission critical loads requiring clean, isolated power.
