Q: What is a servo voltage stabilizer?▾
A: A servo voltage stabilizer is an electromechanical device that automatically maintains a constant output voltage regardless of input voltage fluctuations. It uses a servo motor to control a variable transformer (autotransformer) to regulate the output voltage, providing stable power to connected equipment.
Q: What is the difference between a stabilizer and a voltage regulator?▾
A: A stabilizer typically refers to a device that corrects voltage fluctuations for connected loads, while a voltage regulator generally refers to a more precise regulation device used in power systems. Servo voltage stabilizers are commonly used for industrial and commercial loads.
Q: How does a voltage stabilizer protect equipment?▾
A: A voltage stabilizer maintains output voltage within a safe range (typically ±1%) regardless of input fluctuations. This prevents over-voltage damage, under-voltage burnout, and ensures equipment receives the rated voltage for proper operation.
Q: What is the lifespan of a Dynavolt stabilizer?▾
A: Dynavolt stabilizers are built for longevity with quality components and rigorous manufacturing standards. With proper installation and basic maintenance, they typically last 15-20 years or more.
Q: What is the KVA range available for servo voltage stabilizers?▾
A: Dynavolt System offers servo voltage stabilizers from 1 KVA to 5000 KVA and beyond, in both single phase and three phase configurations, oil cooled and air cooled variants.
Q: What is the difference between oil cooled and air cooled stabilizers?▾
A: Oil cooled stabilizers use transformer oil for cooling, making them suitable for higher KVA ratings and outdoor applications. Air cooled stabilizers use fans for cooling and are suitable for indoor, lower KVA applications where oil is not desired.
Q: What is an isolation transformer and when do I need it?▾
A: An isolation transformer provides electrical isolation between input and output, eliminating common mode noise and providing safety. It is needed when you have sensitive equipment like medical devices, CNC machines, audio equipment, or when electrical safety isolation is required.
Q: What is the difference between a CVT and a servo stabilizer?▾
A: A Constant Voltage Transformer (CVT) is a magnetic device that provides very accurate voltage regulation using ferromagnetic resonance. It offers better regulation but is limited in KVA range. Servo stabilizers can handle larger KVA loads and wider input voltage ranges.
Q: Can you manufacture custom KVA ratings?▾
A: Yes, Dynavolt System specializes in custom manufacturing. We can produce stabilizers and transformers in any KVA rating as per specific customer requirements, including OEM and white-label products.
Q: What input voltage range can your servo stabilizers handle?▾
A: Our servo voltage stabilizers can typically handle an input voltage range of ±30-40% of nominal voltage, maintaining regulated output within ±1% accuracy. Custom ranges can be designed as per requirements.
Q: What is the efficiency of Dynavolt stabilizers?▾
A: Dynavolt stabilizers are designed for high efficiency, typically achieving 95-98% efficiency depending on the load and model. This minimizes energy losses and reduces operating costs.
Q: How much space do I need for installation?▾
A: Space requirements depend on the KVA rating and model. Small units (up to 10 KVA) may be wall-mounted, while larger units require floor space. Contact us for specific installation dimensions.
