5 Pin Mini SPDT Relay 12V 10A 250V PCB Mount Electromagnetic Relay
[Relay Module, Relays] 12V PCB Mount Sugar Cube SPDT Relay – 5 Pin 10A The 12V PCB Mount Sugar Cube SPDT Relay is a compact Single Pole Double Throw (SPDT) electromagnetic relay designed for switching AC and DC electrical loads using a microcontroller, sensor, automation circuit, or other low-power control system. Its compact PCB-mount design makes it suitable for DIY electronics, home automation, security systems, switching circuits, motor control, lighting control, and embedded applications. The relay features a 12V DC coil and a 5-pin SPDT configuration consisting of two coil terminals, COM (Common), NO (Normally Open), and NC (Normally Closed) contacts. When the coil is energized, the internal contact switches between the NC and NO terminals. With contact ratings of up to 10A at 250V AC, 10A at 125V AC, 12A at 120V DC, and 10A at 28V DC, this relay is suitable for a wide range of electrical switching applications. ⭐ Key Features SPDT (Single Pole Double Throw) relay 12V DC coil Compact Sugar Cube design 5-pin configuration PCB mounting type 10A @ 250V AC contact rating 10A @ 125V AC contact rating 12A @ 120V DC contact rating 10A @ 28V DC contact rating Coil resistance: approximately 270Ω Approximately 45mA nominal coil current 50/60Hz frequency specification Fast switching response Suitable for microcontroller and sensor-controlled switching Ideal for automation and control applications 📋 Technical Specifications Product Type: PCB Mount Relay Relay Type: SPDT (Single Pole Double Throw) Contact Configuration: 1 Form C Number of Pins: 5 Coil Voltage: 12V DC Trigger Voltage: 12V DC Coil Resistance: 270Ω Nominal Coil Current: Approximately 45mA Frequency: 50/60Hz Maximum AC Load: 10A @ 250V AC Maximum AC Load: 10A @ 125V AC Maximum DC Load: 12A @ 120V DC Maximum DC Load: 10A @ 28V DC Operating Time: 10ms Release Time: 5ms Mounting Type: PCB Mount Contact Terminals: COM / NO / NC Coil Terminals: Coil End 1 / Coil End 2 🔌 Pin Configuration Coil End 1: One terminal of the 12V DC relay coil Coil End 2: Other terminal of the 12V DC relay coil COM: Common switching contact NO: Normally Open contact NC: Normally Closed contact When the relay coil is not energized, COM is connected to NC. When the 12V DC coil is energized, COM switches from NC to NO. 🛠️ How It Works The relay uses an electromagnetic coil to mechanically switch an electrical circuit. Applying 12V DC to the coil energizes the relay and changes the contact position. A load connected between COM and NC remains connected when the relay is inactive. A load connected between COM and NO remains disconnected until the relay coil is energized. This allows a low-power control circuit such as an Arduino, microcontroller, sensor, timer, or automation controller to control a higher-current AC or DC load. 🔧 Applications Arduino Projects Microcontroller Projects Sensor-Controlled Switching Home Automation Security Systems Lighting Control Fan Control Motor Control Pump Control Power Supply Switching Industrial Control Systems Embedded Electronics DIY Electronics Projects 📦 Package Includes 1 × 12V PCB Mount Sugar Cube SPDT Relay – 5 Pin 10A ⚠️ Precautions Use a suitable 12V DC supply for the relay coil. Do not exceed the specified contact voltage and current ratings. Check the COM, NO, NC, and coil terminals before wiring. Use suitable flyback protection when driving the relay coil from sensitive electronic circuits. Use appropriate suppression/protection components for inductive loads such as motors, solenoids, and coils. Provide sufficient PCB insulation and clearance when switching mains voltage. Disconnect power before changing or modifying wiring. Do not touch exposed mains-voltage terminals during operation.

4s 2a Lifepo4 li-ion Active Lithium Battery Equalizer Balance Board BMS
[Lithium Battery Protection Board] The 4S 2A Active Balancer Equalizer is designed to keep lithium battery cells balanced during both charging and discharging. It continuously monitors the voltage of each cell in the battery pack. When a voltage difference appears, the module transfers energy from higher-voltage cells to lower-voltage cells. As a result, all cells remain balanced and the battery pack works more efficiently. Unlike passive balancing systems, this module does not waste energy as heat. Instead, it redistributes energy between cells. Therefore, the battery pack becomes more efficient and lasts longer. In addition, the balancer automatically starts working when the voltage difference between adjacent cells reaches 0.1V. The balancing process continues until the difference drops to about 0.03V. Because of this smart balancing system, the battery pack stays stable and reliable. This module is suitable for 4S lithium battery packs, including both LiFePO4 and Li-ion batteries. It is commonly used in solar energy storage systems, electric vehicles, and DIY battery projects. 🔹 Key Features Supports 4S LiFePO4 and Li-ion battery packs Active energy transfer balancing Maximum balancing current up to 2A Improves battery efficiency and lifespan Reduces voltage differences between cells Low heat generation compared to passive balancers Automatic balancing during charging and discharging 🔹 Technical Specifications Parameter Specification Battery Type LiFePO4 / Li-ion Battery Series 4S Balance Method Active balancing Maximum Balance Current 2A Operating Voltage Range 2.0V – 4.5V Balance Start Voltage Difference ≥ 0.1V Maximum Balance Current Condition ≥ 0.2V difference Balance Stop Difference ~0.03V Operating Temperature -20°C to 60°C 🔹 Applications This active balancer is suitable for many battery systems, such as: Solar battery packs DIY lithium battery packs Electric scooters and bikes Energy storage systems Backup power systems 🔹 Package Includes 1 × 4S 2A Active Balancer Module
