EX-proof Intirnsic EPS
Product Overview:
LCX Power-GEPS flame-proof & intrinsically-safe EPS emergency power supply is special emergency standby power equipment for gas-dust explosive hazardous locations.
It complies with GB3836 series explosion-proof standards, adopting heavy-duty flame-proof main enclosure plus intrinsically-safe auxiliary circuit dual-safety design.
Adopt full-digital DSP emergency inversion architecture; when mains power fails, it rapidly switches to battery-powered emergency inverter output.
It can supply pure sine-wave AC emergency power and multi-channel intrinsically-safe DC at the same time.
Built-in intelligent BMS battery management system, compatible with lithium-iron phosphate and lead-acid battery packs.
Modular power unit supports capacity expansion and customizable emergency duration. The whole unit passes explosion-proof, damp-heat and anti-impact tests.
It provides reliable emergency power guarantee for emergency lighting, safety monitoring, automatic control instruments under coal-mine underground, petrochemical and other explosive-risk working conditions.
Typical Applications：
· Underground coal-mine emergency lighting, safety monitoring, emergency broadcast emergency power supply
· Petrochemical, oil-gas field explosive hazardous-area fire-emergency equipment standby power
· Tunnel & mine-engineering explosion-proof automatic-control system emergency backup power
· Hazardous-zone evacuation indicator, emergency alarm device power supply
· Metallurgy & chemical-plant flammable-gas workshop key safety equipment emergency power supply
Mining and petro-chemical site emergency load backup power for power-failure
