Technical Specification & User Manual for TOQ3 Automatic Transfer Switch (ATS)
1. Rated Electrical Parameters
Parameter Category
Specification Details
Rated Voltage
Line (L) & Neutral (N) Terminals: 220V AC; Compatible with Frequency: 50/60Hz
Switching Performance
• Power Interruption: Temporary power cutoff occurs during switching operations (normal operational characteristic).
• Switching Time: Maximum 4 seconds (ensures rapid power restoration for critical loads).
Current Ratings & Protection
• 63A Model: Equipped with dual protection mechanisms (over-current protection and short-circuit protection) to prevent device damage from abnormal current spikes.
• 125A Model: Does not include over-current or short-circuit protection (supplementary external protection devices are recommended for safe operation).
• Maximum Current Capacity: 63A / 125A (matches respective model ratings).
2. Core Functionalities
2.1 Automatic Power Transfer Logic
The TOQ3 Dual Power Automatic Transfer Switch is designed for unattended, automatic switching between normal power (primary source) and reserve power (backup source), ensuring continuous power supply to critical loads. Its operating logic follows these rules:
Normal Power Priority: The switch defaults to prioritizing the normal power source. As long as the normal power supply is stable and within the rated parameter range, the switch will remain connected to or automatically switch to the normal power source.
2.2 Operating Modes (Automatic/Manual)
The switch supports two operating modes to adapt to different usage scenarios, accessible via the mode selection button:
Automatic Mode: Press the "Automatic" button to activate this mode. The switch will continuously monitor the status of both normal and reserve power sources in real-time. It will automatically transfer between the two sources based on the pre-set priority logic (no manual intervention required), ideal for 24/7 unattended applications (e.g., residential backup power, small commercial facilities).
Manual Mode: Press the "Manual" button to switch to this mode. In this mode, the automatic monitoring and transfer function is deactivated. Users must manually adjust the switch lever or dial to select the desired power source (normal or reserve).
Frequently Asked Questions
What is the rated voltage and frequency range for the TOQ3 ATS?
The TOQ3 Automatic Transfer Switch is designed to operate on a rated voltage of 220V AC across Line (L) and Neutral (N) terminals. It is fully compatible with power systems operating at 50/60Hz frequency.
Does the power supply get interrupted when switching between sources?
Yes. A temporary power cutoff occurs during the switching operations. This is a standard and normal operational characteristic of this type of transfer switch.
How fast does the switch transfer power?
The switch achieves a maximum transfer time of 4 seconds, guaranteeing a rapid and efficient power restoration to your critical loads.
What is the difference in protection between the 63A and 125A models?
The 63A model features integrated dual protection mechanisms (over-current and short-circuit protection) to shield devices from spikes. The 125A model does not built-in these protections, meaning supplementary external protection devices must be added for safe operating conditions.
How does the automatic power transfer logic work?
The switch defaults to normal power priority. It monitors the primary source in real-time and remains connected to or automatically switches back to the normal power source whenever it is stable and operating within its rated parameters.
Can I operate the TOQ3 ATS manually?
Yes. By pressing the "Manual" button, you deactivate the automatic real-time monitoring and transfer functions. You can then manually toggle the switch lever or dial to select either the normal or reserve power source.
