Technical Specifications
The SSR 32-12 operates from a 120 or 240 VAC auxiliary supply, 50/60 Hz. Voltage sensing range is 80 to 300 VAC. The regulator provides continuous field current of 12 A with a peak capability of 32 A, hence the model designation. The transient response time is less than 30 milliseconds. Ambient temperature rating is -30 to +65 degrees Celsius. The unit is IP20 rated for indoor panel mounting and meets applicable CE and marine classification standards.
Control and Protection
The SSR 32-12 includes adjustable voltage setpoint, stability control, and underfrequency compensation. Protection features include overvoltage protection to prevent generator overvoltage due to sensing loss, overexcitation limiting to protect the field winding, and a soft start function for smooth voltage build-up. The regulator also has an input for external voltage trimming and parallel droop compensation.
Installation and Adjustment
Installation involves mounting the regulator inside a control panel and connecting power, sensing, and field wiring. Adjustment is performed using potentiometers for voltage, stability, and compensation settings. Jumper selections allow the unit to be configured for different input voltage ranges and application modes. Commissioning includes checking voltage calibration and transient response under load changes.
