SAKO / SARVO Stabilizer board (5k / 10k) ( Automatic voltage stabilizer control board) Code: 13927235

The 10kVA servo automatic voltage stabilizer control board (commonly used in brands like SAKO-type systems) manages real-time motor correction, voltage sensing, and safety cut-offs.

Core Technical Specifications

• Compatibility:Single-phase 10kVA (8kW) servo stabilizer systems.
• Input Power/Voltage Sensing:Typically processes AC 140V–250V (or 160V–250V) reference signals.
• Motor Drive Output:Dual DC output terminals (-12VDC to +12VDC) to drive the physical variac servo motor clockwise or counter-clockwise.
• Output Regulation:Maintains stable 220V AC (± 3% precision).

Key Functions & Features

• High/Low Voltage Cut-off:Automatically trips output when input voltage exceeds ~246V or drops below ~184V.
• Delay Timer:Built-in connector port for selectable short/long delay (3 to 5 seconds or extended startup delay) to protect compressor motors.
• Motor Control Interface:2-wire or dedicated harness female jack connecting directly to the servo motor assembly.
• Protections Managed:Overload, short-circuit, and under/over-voltage relay triggering.
