Online Transformerless UPS

Introduction

AF93300 series Online Transformerless UPS 3 phase input and 3 phase output with a capacity covers various power ranges between 80kVA and 180kVA, which is convenient for users to flexibly configure. The product adopts online double conversion design and is based on DSP full digital control to provide stable and uninterrupted power supply for important loads, which can eliminate "power pollution" such as surge, instantaneous high voltage, instantaneous low voltage, wire noise and frequency deviation on the mains, and provide customers with high-efficiency and high-power density power supply guarantee.

Application

Suitable for small and medium-sized data centers, enterprise server rooms, control centers in manufacturing, medical care, schools, transportation, energy and other fields.

As well as precision production and testing equipment in the industrial field such as (SMT placement machines) as key equipment for power supply and protection.

Feature

●3 phase input and 3 phase output

This series of UPS is a Online Transformerless UPS with balanced three-phase input current, which can balance the load of the three-phase power grid.

●Digital Control

All parts of the UPS series are digitally controlled. The UPS has excellent performance indicators, high system stability, self-protection and fault diagnosis capabilities, and avoids the risks of analog device failure, making the control system more stable and reliable.

●LCD Display

This series of UPS uses LCD display, which allows users to more intuitively understand the working status and operating parameters of the UPS, such as input/output voltage and frequency, load size, battery capacity, internal temperature, etc., making all operations clear at a glance.

●Optional External Battery Quantity

The number of external batteries for this series of UPS can be selected according to user needs, and the number of batteries can be selected from 30 to 50.

●Charging Current Can Be Set

This series of UPS can automatically allocate reasonable charging current by setting the battery capacity configured by the user. Constant voltage charging mode, constant current charging mode and floating charging mode can be automatically and smoothly switched.

●Smart Charging Method

This series of UPS adopts an advanced two-stage three-stage charging method. The first stage is high-current constant current charging, which quickly recharges about 90% of the power; the second stage is constant voltage charging, which can activate the battery characteristics and fully charge the battery; the third stage is floating charge mode. This can well balance the goals of fast charging and extending the battery life, saving users' battery investment.

●Intelligent Monitoring Function

When this series of UPS is equipped with an SNMP card, remote monitoring of the UPS can be achieved.

●EPO function

An emergency power off (EPO) button interface is embedded on the rear panel of the UPS unit, and the user can connect an external EPO button. In an emergency, pressing the EPO button can shut down the unit in an emergency; it also has a remote emergency power off function (REPO) .

●Parallel function

More than 4 systems can be connected in parallel redundancy.
