PTC High Voltage Coolant Water Heater

 

PTC High Voltage Coolant Water Heater

 

Product Description

 

PTC water heating assembly can provide heat for the new energy vehicle cockpit and meet the standard of safe defrosting and defrosting. At the same time to the vehicle other need to adjust the temperature of the body to provide heat. 

Features 

• use electric heating antifreeze to heat the interior of the vehicle through the heater core. 

• Installed in a water-cooled circulating system. 

• The heater is gentle and temperature-controlled The power of IGBT is regulated by PWM. 

• It has a short-term heat storage function. 

• Cycle the vehicle to support battery heat management.

• Environmental Protection.

Installation Advice

Control mode:CAN communications 

 

Soft start function: 

PWM soft start PWM from 0% to 100% it uses 30 seconds. This function is used to protect high impulse current and sudden change on high voltage bus. Each path gradually soft start, soft start process ripple Current, impact current small (＜1.3 times the rated current).

 

Restricted features: 

1.temperature limit

• when the temperature of the outlet reaches 80 ° C, the power will be reduced gradually and the water temperature at the outlet will be kept relatively constant.

• When the temperature of any IGBT reaches 85 ° C, the power will be gradually reduced or turned off, and when the temperature is below 80 ° C, the IGBT will resume work, so that the IGBT temperature does not exceed the limit value.

2.Power limit

• Soft start power limit: Soft-start is limited to 3800W per circuit.

• overcurrent protection: If the circuit lasts more than 2 times the rated current for 5 seconds during heating operation, the circuit is considered to be overloaded and will be closed and restarted.
