Overview

The SolaHD STC-DRS-232 is a DIN rail-mountable surge suppressor engineered for precise protection of low-to-medium power industrial control systems. This device clamps transient voltages to a maximum peak of 15V while maintaining a nominal breakdown voltage of 22V, ensuring sensitive electronics remain within safe operating limits during voltage spikes. With a surge rating of 10KA over an 8×20µs waveform, it rapidly dissipates fault energy to prevent damage to downstream equipment such as PLCs, motor starters, and control panels. Designed for continuous operation, the STC-DRS-232 handles a maximum continuous current of 150mA without degradation, making it suitable for power lines and signal circuits in automation environments. Its nominal series resistance of 5Ω limits fault current while minimizing impact on normal operation, providing a balance between protection and performance. The compact DIN rail form factor enables straightforward installation in existing control panels, reducing both time and cost compared to custom mounting solutions. Key applications include protecting DC power supplies, communication interfaces, and sensor circuits in industrial automation, manufacturing, and process control systems. The device’s 5Ω series resistance ensures compatibility with low-power electronics while maintaining reliable operation under transient conditions. For environments where voltage stability is critical, the STC-DRS-232 delivers targeted surge suppression without introducing unnecessary impedance.
  • Maximum peak voltage: 15V for precise clamping
