Complete EPS power supply range and selection guide

This page brings together the available Sanyi Power EPS-SD, EPS-SP and EPS-ST documents across the 43, 53 and 63 series. Selection should verify input and output form, load, output circuits, transfer time, battery and target runtime. Final limits must be checked in the exact model datasheet.

What to confirm before selecting an EPS supply

  1. 1

    Define the load and output

    Identify the emergency-lighting, security or other load, then confirm AC or DC output, voltage and total load.

  2. 2

    Choose the model and circuits

    The catalogue includes SD, SP and ST constructions with different circuit counts. Select from wiring and maintenance needs, not from the series number alone.

  3. 3

    Check transfer and backup

    The catalogue lists a transfer time of no more than 0.25 seconds. Runtime also depends on load, battery capacity and condition, losses and temperature.

  4. 4

    Verify the datasheet

    Download the exact PDF and check wiring, dimensions, environment, protection and project requirements before ordering.

EPS power supply FAQ

Which EPS models are currently listed?

The website lists EPS-SD-4301, EPS-SP-4303, EPS-SP-5303, EPS-ST-4304/4308/4310, EPS-ST-5304/5308/5310 and EPS-ST-63100.

Are an EPS supply and a UPS the same?

No. Output form, transfer method, load profile and system purpose may differ. They cannot be substituted by name alone.

How do I choose between the 43, 53 and 63 series?

Compare output form, circuit count, load and installation requirements in the exact datasheet. The series number alone is not a specification.

How is EPS backup runtime calculated?

Runtime depends on load, battery voltage and capacity, conversion efficiency, wiring loss, battery condition and temperature.
