Product Feature: ITech Battery Testers

IT5100 series is a series of battery internal resistance testers with high precision, high resolution and high speed.

IT5100 adopts AC 4-terminal sensing, that means the tester can test internal resistance and voltage simultaneously with high precision. Resistance resolution is down to 0.1 µ, voltage resolution is 10 µV. Combined with external USB disk, IT5100 is available for long-term statistics calculation. Built-in comparator function, IT5100 can automatically determine whether the battery parameters meet the standards and count pass rate, which is suitable for a variety of battery`s test and pick.

Built-in GPIB / USB / LAN communication interface to support SCPI communication protocol.

Single unit of IT5102 support 16 channels batteries measurement, master- slave connection up to max.17 sets and extension channels quantity up to 272, that greatly improves testing efficiency.

Built-in LAN / RS232 communication interface, the IT5100 series can be widely applied in cellphone lithium batteries, electric vehicle batteries and other batteries inspection and sorting.

The wide measuring range and multi-functions makes the IT5100 series ideal for inspection and sorting of all types of batteries. It can be used to validate various types of DUT's requiring test of internal resistance, contact resistance, Equivalent Series Resistance (ESR) etc.

It is useful in both R&D, production test and other applications.

High-voltage battery pack test eg. electrice vehicles, lithium battery etc.
Battery module testing
Large (low-resistance) cell testing
High-speed mass production testing of coin batteries
UPS inspection
Deterioration and life assessment of alkaline batteries, lead-acid battery
Various contact resistance test
Equivalent Series Resistance (ERS) test

Modular UPS - AHR Series

Supplier Feature:Soltec

MasTec has marketed Soltec since 2000 and has hundreds of these UPSs running now in diverse environments, IT server farms, office, industrial and commercial.

MasTec stocks Soltec and can meet most calls for UPS from stock. We highly recommend these UPSs.

Since 1986, Soltec, an ISO9001 certified company, has been a reputable and leading designer and manufacturer of standard & tailored-made UPS, Frequency Converter and Inverters.

Soltec are CE and UL Compliment UPSs -

Super Efficient Line interactive UPSs
Low Frequensy Pure Sine On LIne UPSs
High Frequency High Efficient On Line UPSs
Home or Commercial Building UPSs that can manage giant battery banks
Pure Sine Totally Galvancially Isolated UPS with hundreds of KW output - Redundant also
Frequency Converters
Rectifiers ( Charger )
Static Transfer Switches
Accessory of UPS

Their in house technology through R&D is extensive. Their 10KA Line interactive low frequency transformer and high efficiency UPS, is still the highest powered units of this type.

Soltec is also a leading supplier of excellent Frequency Converters > choose 50, 60, 400 HZ in or out > both single or three phase models.

MasTec supplies to Oceania many of these Soltec frequency converters each year. Typical applications are for converting NZ 230VAC 50 HZ power to USA 110VAC 60HZ or 230VAC 50HZ to 230 VAC 400HZ aircraft power or the other way around.

Almost all Soltec products can be ordered with an extra transformer to make the output Galvanically Isolated.

We have supplied models up to 20 KVA with these very heavy transformers. In labs and some factory systems this is essential for stable operation of a control system or IT system.

The large Industrial ALP UPSs are always galvanic isolated and are modular growing up to 200KV.
