Frequently Asked Questions (FAQ)

Q: What is the transfer time between power sources for the SJKQ5 series?

A: Transfer times vary based on the frame size and rating. For smaller capacities (up to 100A), it is typically 2 seconds, while intermediate ratings operate at 0.6 to 1.2 seconds, and larger capacities (up to 3200A) range between 1.8 and 2.4 seconds.

Q: What control voltages are supported by this automatic transfer switch?

A: The switch supports multiple control voltage configurations including DC24V, DC48V, DC110V, and AC220V, allowing flexible integration into various power management infrastructures.

Q: What is the functional difference between Type I, Type II, and Type III designations?

A: Type I handles Utility-to-Utility non-recovery mutual backup; Type II handles Utility-to-Utility with automatic transfer and self-recovery; Type III is designed for Utility-to-Generator management with automatic start/stop and recovery.

Q: Can the SJKQ5 ATS be ordered in both 3-pole and 4-pole versions?

A: Yes, the designation code includes configuration options for both 3-Pole (3P) and 4-Pole (4P) across standard and high-amperage models up to 3200A.

Q: Does the system include built-in power fault protections?

A: Yes, advanced models (Types I, II, and III) are equipped with integrated protection mechanisms against phase-loss, overvoltage, and undervoltage conditions.
