7.Temperature Compensation
8.PMBus Communication Interface
HEP-1000 supports PMBus Rev. 1.1 with maximum 100KHz bus speed, allowing information reading, status monitoring, output trimming, etc. For details,
please refer to the User’s Manual.
4.Output Current Programming (or, PC / remote current programming / dynamic current trim)
※ The output current can be trimmed to 20~100% of the rated current by applying EXTERNAL VOLTAGE.

◎ To exploit the temperature compensation function, please attach
the temperature sensor, NTC, which is enclosed with the charger,
to the battery or the battery's vicinity.
The charger is able to work normally without the NTC.◎
