Product details
Product descrtion:
●Working voltage: 220V ● Allow the load to be le than 1000W ●Control switch is suitable for self-locking and self-resetting type ●Two protection normally open protection interfaces ●The rated current of the relay is 30A, which can withstand the power below 1000W. ● board is 2MM high-grade fibergla board ●The copper foil of the is 2 ounces ●The size of the is 77.5MM*88MM. ●The distance of four symmetric holes is 69X79.5MM
The main function:
1. Suppre the inrush current of the power amplifier at startup, because the power of the cla A and high power amplifier is large, the load impedance is extremely low, and the power supply filter capacitor capacity is too large, which leads to exceive current at the startup of the power amplifier, which easily damages the rectifier bridge and damage filter capacitor. 2. When the temperature of the heat sink of the power amplifier board exceeds 75 degrees, the board can cut off the power immediately, and the power amplifier will not be overheated and burned. Until the temperature of the heat sink drops below 75 degrees, the power amplifier can be turned back on, otherwise the power amplifier can't be turned on. ● Schematic: For reference only, subject to change without notice.!!! ●When the start switch KT is preed, if the protection port is normally open (if the port is closed, it cannot be started), the start of the start, the work indicator LED is on, the current limit relay is closed (K01), the current limit module is connected to the 220V loop current limit, delay 3 seconds, the through relay (K02) is closed, the current limit is ended, the delay is 1 second, and the current limiting relay is disconnected. If the startup board is working normally, when any protection port SW is closed, the startup board is turned off. ● This version has a significant improvement with other versions of the soft start board. Other versions of the starter board open the current limit relay without delay when the relay is closed at startup. Due to the mechanical delay of the relay, the 220V circuit will appear. A brief open circuit causes the load to experience a brief inrush current. ●The startup board start switch automatically adapts to the self-locking switch and the self-reset switch, without changing the startup board settings.
Buyer's question:
●What is a self-locking switch and what is a self-resetting switch ● A: Pre the switch to turn on, release the switch to open, it is the self-reset switch; pre the switch to turn on, release or turn on, then pre and then release to open, it is a self-locking switch. ● How big is the start switch? ● A: It can be used within 1A. ● Can the start switch of the starter board be self-locking or self-resetting? ● A: All are ok, the starter board will automatically adapt to the self-locking switch or self-reset switch, without manual intervention. ● If the AC 220V output terminal is not connected to the load (), why is there a 220V voltage output when the startup board is not started? ● A: This is because the arc-extinguishing capacitor is connected in parallel between the relay contacts. As long as the 220V output terminal is connected to the load, it can be soed.
