TKR Single-Phase Electronic Voltage Regulator
Every regulator covered so far has something that moves — a carbon brush riding a coil, a geared motor, an induction mechanism turning under load. The TKR doesn’t. It’s a fully electronic, chip-controlled design: a digital control program monitors voltage and switches regulation electronically, with no mechanical wear parts and low standby power draw that supports continuous, long-duration operation. Over-voltage, under-voltage, overload, over-temperature, and startup-delay protection are all handled by the same control chip rather than separate relays, giving the TKR a more compact, lower-maintenance footprint than a servo-driven unit of similar capacity. It’s built for the equipment where any downtime for brush replacement or motor service isn’t an option — smart home electronics, industrial control panels, and electronic instrumentation — available from 1.5KVA to 5KVA.
Key Features
No brush, no motor, no wear-and-tear maintenance schedule — just a chip watching the voltage.
Digital Chip Control
A programmable control chip governs regulation electronically, replacing the analog circuitry and moving parts found in earlier-generation stabilizers.
No Mechanical Wear Parts
Fully electronic regulation means no carbon brush or drive motor to wear out or service over the unit's operating life.
Low Standby Power Draw
Minimal self-power consumption supports continuous, long-duration operation without excessive energy overhead.
Five-Function Protection Suite
Over-voltage, under-voltage, overload, over-temperature, and startup-delay protection are integrated into a single control system.
Multi-Function LED Display
Clear LED readout for real-time voltage monitoring in a compact panel.
Startup Delay Protection
A 5-second delay after power-on before voltage output begins, protecting connected equipment from startup transients.
