AC Loads

AC Loads are a complex piece of equipment much more so than DC Loads.

All these instruments can be interfaced and controlled by computers to make Test Systems automatic. The interface can be LAN (Ethernet), GPIB, (General Purpose Interface Bus) or Serial comms.

All these Test instruments have hundreds of commands built in that you can control with a PC via the interface to make them do certain things for you and they send back heaps of data as they do their testing.

Usually there is a bank of Instruments in a Test Suite, the Itech IT8600 would only be one of several usually.

This field of Test Instruments is huge and very sophisticated.

Anyone building a device that makes AC power would need a device like the Itech IT8600 to verify and document its performance. This is called Characterising or learning the devices personality under every conceivable operation mode.

Applications:

UPS

Inverter

Frequency converter

Generator

AC power supply

Electronic components

 

IT8600 is ITECH latest series of AC/DC electronic loads with power range 0~14.4 kVA and adjustable frequency 45 Hz ~ 450 Hz. The unique oscilloscope waveform display function of IT8600's can display input voltage & current as waveform. It is equipped with measurement modes for different parameters such as inrush current, peak value, effective value, PF (power factor). Voltage harmonics measurement capacity is up to 50th. The built-in RS232, GPIB, LAN and USB communication interfaces are for reliable and fast control. IT8600 is the perfect solution for testing UPS, inverters, AC power supplies and relevant AC electronic components etc.

IT8600 Features
- Frequency range: 45 Hz~450 Hz
- Power range: 0~14.4 kVA
- Voltage range: 50~420 Vrms, 15~260 Vrms
- Current range: 0~1 60 Arms
- Parallel connection/ three-phase control *1
- 7’’ LCD screen
- Oscilloscope function supporting display of voltage and current waveform
- High-speed AD sampling, real-time capture waveform
- Measure Vrms, Vpk, Vdc, Irms, Ipk, Idc, W, VA, VAR,CF, PF and FREQ
- Measures THD ( V ) up to 50th Harmonic
- AC electronic load: CC/CR/CP mode
- DC electronic load: CC/CR/CP/CV mode
- External 0~10 V analog control input, voltage and current analog monitoring function
- OTP, OCP, OVP, UVP and OPP protection function
- GPIB, LAN and USB communication interfaces and external USB flash disk interface

* 1 IT8615 and IT8615L are with the function

The ELPA-SINE series of programmable electronic loads feature a comprehensive set of both AC and DC test functions.
When in constant current operation the user can select between sine, square and DC waveforms. An adjustable frequency up to 440Hz is provided. Peak currents can be simulated with the crest factor mode. A leading or lagging power factor can be set with adjustments from unity to 0 lagging or leading. The desired wave can be recalled from the front panel or selected via an optional computer interface. The load can also be operated in constant power, voltage, resistance or linear CC modes.

Multiple inbuilt tests include UPS efficiency, PV inverter efficiency, UPS back-up time, battery discharge time, UPS transfer time, short circuit and fuse/breaker trip testing. Other interesting features of the ELPA-SINE include a Turbo mode which can test currents up to double the maximum current of the unit up to 1 second, ideal for inrush current testing.

The 4 digit display simultaneously provides actual values taken by the load. Users can toggle between various measurements for: voltage, current, power, frequency, crest factor, power factor and harmonics. On request the load can be built with a GPIB, RS-232, USB or LAN remote control interfaces. A host of protection features guard the unit against over power, voltage, current and temperature.
