E-load can simulate the real environment of the load (electric), the general power of the relatively stringent requirements of manufacturers around the electronic load to test the quality of power supply. It has a good multi-functional, you can adjust the size of the load, as well as short-circuit, over-current, dynamic, and so on, it should be said that all of the power supply manufacturers will be useful, but there must be.
The principle of electronic load control with power MOSFETtransistor, or the introduction flux (the volume size of the dutycycle), the dissipation by power control power consumption ofelectric power equipment, it can accurately detect the loadvoltage, load current accurate adjustment, as well as Therealization of load Short-circuit simulation, the simulation is theemotional load capacitive and resistive, capacitive load currentrise time. General switching power supply debugging testing isindispensable.
Supported by electronic resistors, inductors, capacitors,transistors, integrated circuits components.
1, is designed to:
Friends should be completed by the demand for digital electronicdesign load
2, the main performance indicators:
2.1 maximum power dissipation: 100W.
2.2 The maximum output current: 10A.
2.3 maximum input voltage: 100V.
2.4 mode of operation: voltage (voltage stability of ± 5%), current(current stability of ± 5%), Constant resistance (resistancestability of ± 5%).
2.5 Protection: over-current protection overload protection
2.6 show voltage and current accuracy: 3 V voltage display showsthat the largest display 99.9V fixed decimal point.
4 ammeter, the largest show 10.00A fixed decimal point.
Status Indicator 2.7: the current state of work instructions(constant voltage, constant current, constant resistance).
2.8 input buttons to control input voltage and current signals.
3, reserved for software: no hardware changes to the softwareupgrade enables the following features
Is scheduled to 3.1 (current, voltage, resistance) value. If we areto 3A current to the battery discharge current can be first toenter the E-3A current pre-load and then connected to the powersupply, electronic load current 3A will be to discharge thebattery.
Taiwan's more than 3.2 e-load work together, they can only use oneof the panels. When dozens or hundreds of Taiwan's electroniccomponent of a load test system, this approach can significantlyreduce the cost.
3.3 synchronization (multi-load work together with all therequirements of the work of the same parameters, can simultaneouslyfunction, so each machine should eliminate the need for settingparameters.
3.4 Save parameters: When used in the production of electronic loadline, for product data and settings preserved, when the nextproduct, as long as the reproduction out of tune on the use of theline, and do not have to re-design parameters.
3.5 curve parameters: the need for many products such as thecharger or power to do in different circumstances, the currentchanges in voltage, or at different voltage under the currentchanges, this feature allows the testing of equipment specified bythe parameters automatically Control input signal.
3.6 preservation of data functions, for a small amount of data canbe stored in single-chip, the larger the amount of data through theserial data transmitted to the massive computer's hard drive.
