Electric Water Heating Heater Instructions-2
1. Operation
The control mode of pure electric water heating heater is mainly divided into ship type switch control and digital display temperature control panel control. The ship type switch control mode is convenient and easy to install, and the heater will work according to the established procedure. The digital display temperature control panel can accurately control the temperature in the carriage through the supporting
control panel.
Selection of supporting harness. The shorter the control line, the better, so as to ensure that the voltage will not drop too much. The maximum length is 10m and the cross section is at least 1.5mm ². If longer wires must be used, relays need to be added to the line to disperse the circuit power and limit the length.
At the beginning of design, considering the different needs of users, customers can decide the matching high and low voltage connectors. But must meet
High voltage plug: over current higher than 45A,
The cross section of matched high-voltage cable shall be at least 6mm ².
Low voltage plug: 6pin connector
The cross section of the matched low-voltage cable shall be at least 1.5mm ².
1.1. Selection of ship type switch control mode
A ship type switch with indicator light can be configured to feed back the signal that the heater has worked normally to the driver. The switch carrying current must reach 1.5A. If the operation display is integrated into the external circuit control, it must require a maximum current of 250mA and a voltage range of 18 to 30V.
Pure electric water heating heater is controlled by low pressure. If the low pressure is not powered on, the heater will not work. If the control line is bridged, the heating system will be started after receiving the signal under the working voltage of 600V.
When selecting the wiring harness, we need to pay attention to the calculation of overload current. The current of the three products we mainly promote is about 30A. Considering that the electric heater has at least 1.5 times the impulse current, 6mm is recommended for the selection of cables ² Special high voltage EV wire for electric vehicle. If electromagnetic shielding is required, shielded connectors and shielded cables can be configured.
