The TN1215-600B with STMicroelectronics SCRs 12 Amp 600 Volt manufactured by STMicroelectronics is a silicon-controlled rectifier (SCR) module designed to control and manage high-current power supplies. It is specifically designed to be used in medium- to high-voltage applications, such as SP40 power supplies, pole-charging systems, and lighting systems. The TN1215-600B is made with 12 Amp peak of high efficient current control and comes with 600 Volt breakdown voltage to protect against damage caused by overloads. It also features zero-cross turn-on for high-speed turn-on response. It is equipped with soft-start for smoothing inrush currents, reverse-blocking for preventing current flow in reverse, and over-voltage protection to ensure there is no damage to the power supply due to high or low-voltage power.
