Technical Parameters

A. Feedback energy absorption

TH6600L series feed-back programmable high-power DC electronic load with feed-back energy absorption function, up to 93% energy feedback efficiency, can be directly returned to the power network directly after the use of electricity, rather than ordinary power supplies as directly as thermal energy consumption, greatly reducing the cost of electricity users.

Due to its direct electrical energy feedback, it avoids the large volume and heat of the instrument brought about by thermal energy consumption, as well as the expenses brought about by the use of air conditioning or other refrigeration systems in order to emit heat; it also reduces noise and avoids the greenhouse gases or hazardous gases produced in the process of refrigeration, which are harmful to the environment.

Another benefit of the feed-back feature is that a single unit can deliver high power in a small footprint (up to 15kW in a standard size of 3U height), which greatly saves the volume required to house the instrument.

B. Master-Slave Mode Parallel with Extended Inputs

Since a single machine supports a maximum input of 360A and a maximum power of 15kW, for higher power or current outputs, it is necessary to output multiple instruments of the same model in parallel.

TH6600L series supports parallel operation in the mode of master and slave. If more than one instrument is in parallel, one of them should be set as the master, and the rest of the instruments should be set as slaves, so that all the slaves can be controlled by the master, and the whole parallel system can be regarded as a single instrument operation at this time.

Master-slave mode parallel support for 1 mainframe, up to 15 standalone units, and a total of 16 units.

C. Data logging function, timing function

During product testing, it is often necessary to record product measurement parameters in real time for product quality analysis or test result traceability.

The built-in data logging function of TH6600L series supports to record the current measured voltage, current, power, resistance, etc. of the instrument to the cache by time interval, set the number of records or timer, and automatically save the test results to an external USB flash disk with CSV file format.

The timing function supports cutting off instrument outputs/inputs in a countdown mode.

D. Built-in function generator

The TH6600L series has a built-in true function generator applied to output voltage or output current.

The instrument has built-in standard waveforms such as sine, triangle, square and trapezoidal waveforms, which can be recalled and output at any time.

The instrument supports test sequences or arbitrary signal generators to generate more complex function signals, which can be divided into 99 groups of sequences for R&D and product testing. The generated function signals and sequences can be stored to a USB flash drive for easy recall.

E. Advanced Functions: List Test

The TH6600L series advanced features support list testing, for those who need complex test steps, they can be performed through a list test sequence.

The list test supports source/carrier voltage, source current, carrier current and time settings, and up to 99 groups of test sequences can be set, and the test sequences can generate arbitrary wave files for function signal generator to call.

F.Advanced Functions: Battery Test

The TH6600L series advanced features support battery or supercapacitor testing with 2 integrated test methods.

1. static test

Static testing of the discharge process and capacity

2. Dynamic testing

Test dynamic discharge, dynamic test, can test the dynamic characteristics of the battery

G. Advanced Features:PVbeta (software)

TH6600L series advanced function supports PV PV test function and easy testing of PV panel PV function.

Simple PV testing is relatively simple, requiring only the setting of Uoc (open circuit voltage), Isc (short circuit current), Umpp (voltage at the maximum power point) and Impp (current at the maximum power point).

After loading and running, the interface can be loaded at any time to change the illumination value, that is, the corresponding output value can be obtained.

H. Advanced Features:MTTPMaximum power point tracking test

Since the PV Simple PV Test function is too simple to automatically track the PV maximum power point, the TH6600L series provides an advanced MTTP function to automatically track the PV maximum power point.

The MTTP function supports the following four test methods:

1. MPPT1: Find the maximum power point, stop when found

2. MPPT2: Quickly find the maximum power point, after finding it, track the maximum power point in real time according to the set value.

3. MPPT3: Real-time tracking of maximum power points based on input maximum power points

4. MPPT4: Read the relevant .CSV file on the USB flash drive to find the maximum power point in the customer's setpoints

After loading and running, the corresponding maximum power point can be obtained.
