Protection

Input Over Voltage

Unit must be safe for input voltage up to 150VAC RMS (and up to 215V peak), need not be operating. Above this level the unit may be damaged.

Reverse Battery Polarity Protection

Non-destructive reverse battery polarity protection with fuses. Unit shall not sustain damage and shall meet all specifications after fuse replacement.

Input Under-voltage

Unit must not be damaged for all input voltages from 0-300VAC. Shutdown or input current limit or other means may be applied when

input voltage is out of normal operating range.

Output over voltage

12/24V mode

12VDC.

Unit will shut down if

Vcharging > Vcharging (target) + 1.0VDC for more than 2 seconds; unit will restart when voltage <=

Vcharging (target) for more than 2 seconds.For battery OVP the unit will restart in the same stage.

24VDC.

Unit will shut down if

Vcharging > Vcharging (target) + 1.5VDC for more than 2 seconds; unit will restart when voltage <=

Vcharging (target) for more than 2 seconds.For battery OVP the unit will restart in the same stage.

Charger over temperature protection

The internal temperatures of the charger will be measured by NTC. Based on these measurements,

unit will shut down if the temperature exceeds 105°C.

Unit will restart when environment temperature cools to 95°C.

BTS(Battery Temperature Sensing)

The battery temperature sensor allows the charge controller to

continuously adjust charge voltage / charge current based on actual battery temperature.

When the battery temperature is over 40°C, unit will reduce the charging voltage to Float voltage, also it will reduce the Max charging current by 10% with every two degree of temperature rise.

When the battery temperature is over 50°C, unit will shut down.

Environmental
