250W Upgraded Electronic Load Meter 1-100V Input Voltage LED Display with Power Lockout Current Display Temperature Protections Fan Delayed Shutdown Auto-correction Functions This electronic load meter featuring wide voltage input ranges, it can accept an input voltage of 1-100V, the voltage out of ranges will be indicated by the digital tube flashing and locked with no output. With the real-time current display function, when the output current is greater than 0, the actual working current and regulation current will be displayed alternately, flashing is the actual output current, it is convenient for users to understand the real-time working status of the device. With the automatic correction function, if the voltage and current deviation are found to be more than the specified value during the production test, it can be automatically corrected by simple operation to ensure the accuracy of the equipment.  Features: Featuring wide voltage input ranges, it can accept an input voltage of 1-100V, the voltage out of ranges will be indicated by the digital tube flashing and locked with no output.  The power lock function allows you to lock the power as needed. For example, the input is 100 V, the output current is not more than 1 A, and the software locks have nothing to do with the current adjustment knob. With the real-time current display function, when the output current is greater than 0, the actual working current and regulation current will be displayed alternately, flashing is the actual output current, it is convenient for users to understand the real-time working status of the device. With the temperature protections function, when the NTC temperature probe accesses the voltage digital tube will alternately display the input voltage and temperature (the probe needs to be fixed in the heat sink or MOS tube) when the temperature exceeds 80℃, and the current will be lowered to stop the output, to protect the safety of the equipment. Below 50 degrees to re-open, and the temperature protections will be invalid without access to the probe. With the fan delay-off function, when the current regulation is adjusted to 0, the fan will be delayed off for 1 minute.  With the automatic correction function, if the voltage and current deviation are found to be more than the specified value during the production test, it can be automatically corrected by simple operation to ensure the accuracy of the equipment.  Simple operation, when shutting down, you need to disconnect the input current first, and then shut down the 12 V powersupply of the electronic load, to avoids the EMF burning the MOS tube.  Although the RS485 communication function is not turned on at present, this function is reserved to provide the possibility of prospect upgrades and expansion.
