HEP-1000 Temperature compensation
◎ To enable temperature compensation function, connect the NTC sensor that comes with the supply to RTH+ and RTH-. Default
setting is -3mV/Cell/℃, compensation values also can be adjusted to 4mV/Cell/℃ or -5mV/Cell/℃ through the SBP-001, the
charge programmer.
◎The input voltage range is AC90~305V or DC250~431V.
◎To ensure proper operation, AC input should be within the pre-specified range. A wrong input will cause the supply unit
operating improperly, losing PFC function or even damaging the unit in a worst case scenario.

In addition, users are able to customize their own charge curves, which will be stored to "default" after modification.
Constant voltage can be set by Command B1h CURVE_CV; Float voltage can be set by Command B2h CURVE_FV;
Charge current of stage 1 can be set by Command B0h CURVE_CC; Taper current level for stage 2 to stage 3 can be
set by Command B3h CURVE_TC. Please refer to the following PMBus Command List in 3.12.7 for detailed information
on commands and parameters.
NOTE: 1.The updated charging parameters are saved into EEPROM. The updated charging curve takes effect after HEP-1000 is restarted.
2. When charging curve is enabled, the following commands will be invalid while other PMBus commands are effective:
Command 01h OPERATION (regarding Remote ON-OFF function), Command 22h VOUT_TRIM (regarding Output
voltage programming function) and Command 46h IOUT_OC_FAULT_LIMIT (regarding Output current programming function).
