10A Intelligent Solar Controller with LCD
This is a Digital PWM Solar Charge Controller for the lead-acid batteries connected to a solar power system. When connected to the battery, this charge controller automatically detects the battery voltage from 12V-24V. This charge controller has some advanced features like built-in short circuit protection, open-circuit protection, reverse voltage protection, overload protection, etc which makes it ideal for grid power systems.
12V relay
2-channel 5V relay
2-Channel 5V Relay Module is a relay interface board, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on. It uses a low level triggered control signal (3.3-5VDC) to control the relay. Triggering the relay operates the normally open or normally closed contacts.
4-channel 24V Relay
4-channel 5V Relay
5V Relay
Triggering the relay operates the normally open or normally closed contacts. It is frequently used in an automatic control circuit. To put it simply, it is an automatic switch to control a high-current circuit with a low-current signal. 5V relay signal input voltage range, 0-5V. VCC power to the system.
