N68000 Series High Power DC Electronic Load
N68000 series has a comprehensive MOS protection circuit. No matter how much MOS is damaged, it will not cause short-circuit between the positive and negative polarity or the positive polarity and the control circuit. The damage of some MOSs does not accelerate the damage of others, which can be used continuously.
■ By distributed design, it is easy to replace or add power modules and is convenient for maintenance and power expansion.
N68000 series supports two modes for short circuit: manual and lock.
Manual: N68000 will be short-circuited when Short button is pressed.It will stop short-circuiting when button is released. Manual mode is suitable for debugging or R&D, avoiding measurement accidents dueto misoperation.
Lock: N68000 will keep short-circuiting when Short button is pressed.It will stop short-circuiting when the button is pressed again. Lock mode is suitable for long-time short-circuit test.
N68000 series provides three options for dynamic: continuous, toggle and pulse. The dynamic rate is up to 20kHz and can be adjustable.This function is often used to test power supply transient performance,battery protection board protection performance and battery pulse charging.
Transient over-power loading capability
In transient high power applications, users do not need to select models according to the Max. power. Take DC motor start-up simulation for example. The transient power at start-up is usually several times of the rated power. It can also test the transient overload performance of power supplies and the transient high-power discharge of power batteries.
Users can control load voltage and current via external analog input. 0-10V input through the external programming interface corresponds to 0-full scale output on the load.
0-10V analog output at the current monitoring output terminal corresponds to 0-full scale current. Users can use a voltmeter or oscilloscope to monitor the current variation.
Programmable slew rate
Rise and fall slew rates are settable to prevent overshoot and meet different test demands.
The conversion slew defines the current or voltage transition rate when the on-load main value of N68000 changes. When the slew is set to the maximum value, the transition time between the main value and the transient value is minimal.
