EX-proof Intirnsic UPS
Product Overview:
LCX Power-GUPS flame-proof & intrinsically-safe UPS is an uninterruptible power supply specially developed for explosive hazardous areas.
It complies with GB3836 series explosion-proof standards, adopting heavy-duty flame-proof main enclosure plus intrinsically-safe auxiliary circuit dual-safety design.
It adopts full-digital DSP online UPS architecture, realizing zero-time switching between mains power and battery backup.
It can output pure sine-wave AC and multi-channel intrinsically-safe DC at the same time. Built-in intelligent BMS battery management system, it supports lithium-iron phosphate and lead-acid battery packs.
Modular design supports capacity expansion and backup time customization.
The whole unit passes explosion-proof, damp-heat and anti-impact tests. It provides continuous, safe and reliable uninterrupted power guarantee for monitoring, communication, safety instruments under coal mine underground, petrochemical and other gas-dust explosive hazardous environments.
