Product Introduction

Double-break transfer switch is a microcontroller-based automatic transfer switch with dual power supply (L1/L2) automatic switching capability and support for priority phase selection. It features a digital display of operating voltage and current, with a measurement accuracy of Class 0.5. Users can set various parameters via buttons to achieve power-on delay, switching delay, timed on/off, over-voltage protection (adjustable from 120V to 300V), under-voltage protection (adjustable from 80V to 210V or OFF), over-current protection (adjustable from 1A to 63A/100A, including action delay and continuous trip count limit), and temperature protection (adjustable from 40°C to 120°C). The product is designed for DIN rail mounting and is suitable for power distribution applications requiring intelligent power management and safety protection.

Program Description

Set character	Technical parameter	Set range	Default value	Step forward	Function description
P-1	Power-on delay time	1S-999S	5S	1S	After external power cut, the time needed for power-on when power recovery.
P-2	Recovery/Switch Time	1S-999S	10S	1S	Is the time required for the line to return to normal or switch to a working line.
P-3	Timed off	OFF-0.1m-999m	OFF	0.1m	Can be used to timed off the device.
P-4	Timed on	ON-0.1m-999m	ON	0.1m	The P-3 timer off parameters must be changed before the timer on parameters can be adjusted.
P-5	Input phase priority selection	L1-L2-ATO	L1	1	Operating mode: When L1 or L2 is selected, it's a priority phase selection; ATO: Non-priority mode, fixed to the current phase.
P-6	Over-voltage protection value	120V-300V -OFF	270V 140V	1V	When the voltage of one phase is over the set value, the protector will cut off this phase and switch to the next phase according to the sequence set in P5. When all voltage is over the set value, the protector will cut off all lines.
P-7	Under-voltage protection value	OFF-80V-210V	170V 90V	1V	When the voltage of one phase is under the set value, the protector will cut off this phase and switch to the next phase according to the sequence set in P5. When all voltage is under the set value, the protector will cut off all lines.
P-8	Voltage calibration	±9.9%	0	0.1%	Correct the voltage error.
P-9	Over-current protection value	1A-63A/100A -OFF	63A 80A	1A	When the current is higher than the set value, the protector will cut off the line. When setting OFF, the protector will turn off over-current protection function.
P-10	Current calibration	±9.9%	0	0.1%	Calibrate current current value.
P-11	Overcurrent protection action time	0.1S-30S	1S	0.1s	When over current, the time needed for protection action.
P-12	Times of continuous over current protection	OFF-1-20	OFF	1	When the times of continuous over-current protection exceeds the set value, the protector will cut off the line, then it needs to be opened manually.
P-13	Temperature protection	40°C-120°C	90°C	1°C	After temperature protection, the hysteresis value is restored to 10°C.
