BUS-11 is designed to control the power of active loads (electric heaters, lamps, resistive elements) using the burst-firing (cycle control) method. Its operating principle is based on supplying an external analog control signal, which determines the duration of the triac’s ON state—i.e., the number of AC mains cycles during which the load remains powered. Switching occurs at the zero-crossing point of the AC voltage, which significantly reduces electromagnetic interference (EMI) and increases system reliability.

⚙️ Functional Features of BUS-11

• ✅ Automatic power control of active loads according to analog input signals:
  • 0…5 mA
  • 0(4)…20 mA
  • 0…10 V
• ✅ Supports load control through:
  • Built-in triac
  • External triac
• ✅ Suitable for controlling active loads (primarily resistive type)
• ✅ Control of high-power triacs using burst-firing method — efficient for medium and high-power applications
• ✅ Supports single-phase loads

The module is designed to control the AC voltage supplied to active or active-inductive loads using the phase-angle control method with a triac. Phase-angle control enables smooth adjustment of effective power by applying a gate pulse to the triac at a specific phase angle during each AC cycle.

⚙️ Functional Features

• ✅ Phase-angle power control within the range of 0…180°
• ✅ Support for analog control signals:
  • 0…10 V
  • 4…20 mA
  • 0…5 mA
• ✅ Operates with a built-in or external triac
• ✅ Compatible with active and active-inductive loads
• ✅ Optical isolation of input, output, and power circuits for galvanic separation
• ✅ Mains synchronization via zero-crossing detector
• ✅ Protection against overvoltage and short circuits (with external components)
• ✅ Supports single-phase load operation (230 V / 50 Hz)
