Product Description
ESTD Series UPS is adopting the technology, which combined with the world's most advanced
DSP digital control technology currently, and IGBT high frequency Pulse Width Modulation
technique (PWM). Double-conversion online topology design makes the output frequency of
UPS, which used for tracking, phase-locking, voltage regulator and filter out noise, interference
from the power grid fluctuations in pure sine wave power supply, and make the UPS more
comprehensive and perfectly protection for the users.

High charging capability
Cold start and mains start function
Standard configuration with output isolation transformer
Suitable for all kinds of loads (resistive, inductive and non-linear loads etc)
Other options(parallel kits, input isolation transformer, bypass isolation transformer and harmonic suppressor)
High overload capability (up to 150%)
DSP (Digital Signal Processors) technology
Bypass dual DSP control design to enhance more reliability
Single / single-phase models with on-line double conversion technology
Advanced communications RS232 and USB ports (standard), SNMP, dry contacts and RS485 (options)
Redundant & parallelable with advanced parallel current-sharing control technology, Optional N+X redundancy parallel up to 8 units
Superior protection (surge, short-circuit, over-voltage, undervoltages, overcharge, overload, over temperature, reverse connection protection etc.)
