Basler MVC-300 Electronic Manual Excitation Controller

Basler MVC-300 Electronic Manual Excitation Controller

Product positioning and core role

MVC-300 is a manual backup voltage regulation unit specially designed by Basler for excitation systems, serving as an emergency redundant equipment for automatic AVR faults.

Usage scenario: When the automatic voltage regulator (AVR) and PT voltage sampling circuit are damaged or fail, the original automatic voltage regulation circuit can be completely isolated, and the excitation can be manually adjusted to maintain the generator output, ensuring continuous power supply for critical emergency loads such as hospitals and data centers until equipment maintenance is completed;

Scope of adaptation: Compatible with all Basler analog/digital excitation voltage regulators with a continuous output of 7A or less;

Supporting components: Document annotation SRK-12 supporting kit.

Core product features

All solid state without discrete mechanical contacts, stable and durable circuit;

The power supply is compatible with two single-phase voltages of 120Vac/240Vac and can adapt to a wide frequency range of 50-320Hz;

Multi level DC excitation output, adapted to different excitation winding impedances;

Built in automatic excitation and voltage building circuit, which can automatically establish excitation when the residual voltage of the unit is insufficient;

Small and lightweight structure, compact size, supports internal installation of cabinet doors/control cabinets;

Spot supply, some models support remote excitation lifting operation;

Industrial grade sturdy design, validated through long-term on-site conditions, with high reliability in emergency situations.

Product advantages

Lightweight and miniaturized, compared to the large manual controller MVC-104/108/232, it saves more cabinet space;

Extremely low overall power consumption of only 30W, low long-term standby energy consumption;

Wide temperature range, strong resistance to vibration and impact, suitable for harsh environments such as mobile units, wilderness, and computer rooms;

Multi voltage excitation output gear, compatible with the vast majority of small and medium-sized brushless excitation generators;

Equipped with an excitation circuit, no additional magnetization operation is required;

The all solid state circuit has a low failure rate and is used as a backup excitation for long-term stable and reliable standby.
