PIP ELSAP04:2009 Download

The PIP ELSAP04:2009 standard is a specification that outlines the requirements for a complete uninterruptible power supply (UPS) system. The standard covers the design, fabrication, inspection, testing, shipment, and documentation of both pulse width modulated (PWM) and ferroresonant-type UPS systems.

A PWM-type UPS system consists of various components, including a rectifier/charger, inverter, static bypass switch, manual bypass switches, transformers, and accessories. On the other hand, a ferroresonant-type UPS system includes a rectifier/charger, inverter, constant voltage or ferroresonant transformer, static bypass switch, manual bypass switches, transformers, and accessories.

The purpose of this standard is to ensure that UPS systems meet the necessary requirements for uninterrupted power supply. This includes providing continuous power during power outages or fluctuations and maintaining stable voltage output. Compliance with this standard ensures the reliability and performance of UPS systems in various applications and industries.
