Original Mebay ATS320AC Generator ATS Controller Panel
The ATS320AC model from Auto Engineering provides intelligent dual power switching for reliable mains-to-generator transfer. Real-time monitoring covers voltage and frequency, while the LCD screen displays faults for quick troubleshooting. It supports a bilingual interface (Chinese/English) and USB programming for parameter configuration. Best for buyers seeking an affordable, dual-power ATS with straightforward setup and basic fault visibility. Caution: Ensure your system voltage and phase match the panel’s capabilities before wiring.
YOKDEN ATS520 Generator Genset Controller Panel
The ATS520 from YOKDEN uses 32-bit microprocessor technology and supports a wide voltage range (DC 8-36V or AC 90-280V). It features a 3.5” LCD screen and USB interface for parameter setup and real-time monitoring. It can manage two generators for cycle and balanced operation, with independent over-current and trip warnings for S1/S2. This makes it well-suited for users needing dual-generator coordination and detailed status reporting. Caution: Complex setups benefit from careful wiring and adherence to the manual to avoid misconfiguration.
Automatic Transfer Switch Controller by Jectse
The Jectse ATS Controller emphasizes modular installation with EU standard terminal blocks, simplifying wiring tasks. It supports both manual and automatic operation and allows flexible starting conditions for the unit. Best for installations where clean wiring and easy future upgrades are priorities. Limitation: Feature depth may be lighter than higher-end controllers, so verify required monitoring parameters before selecting.
Diesel Generator Automatic Transfer Switch Controller (ATS320AC)
This ATS320AC-based controller focuses on automatic or manual control for dual power sources, typically mains and generator. The LCD can display multiple faults simultaneously, aiding protection when the generator is not running smoothly. It supports various AC configurations and provides essential data such as mains and generator voltage, frequency, switch status, and running time. Choose this if you need broad acceptance across common AC systems and clear fault visibility. Caution: Confirm compatibility with your generator’s starter and control wiring before installation.
YOKDEN Genset Controller Panel 4.3 Inch LCD (DC72DR)
This YOKDEN DC72DR controller is designed for Diesel and Gas gensets, offering a 4.3″ color LCD with a comprehensive UI. It monitors engine and mains data, displays faults, and supports USB/CAN/RS485 interfaces for data exchange. Best for professional installations needing detailed engine and electrical parameter visibility. Limitation: The broader feature set may require more setup time and a more capable host enclosure for stormproofing and secure mounting.
Buying Guide
What to consider when selecting an ATS panel for your generator:
- Voltage and phase compatibility: Confirm the controller supports the system voltage (120/240V, 1P2W; 208/230/240V, 3P4W) and whether you need single-phase or three-phase operation.
- Automatic vs. manual operation: If you want hands-off transfer, choose models with reliable automatic transfer and clear fault logic. Manual modes are helpful for testing or unusual conditions.
- Monitoring depth: Decide how much parameter data you need. Simple fault indicators suit basic protection, while comprehensive parameter lists (engine sensors, mains data, power metrics) aid diagnostics.
- Wiring practicality: Modular or terminal-block designs simplify installation and future upgrades. Consider enclosure IP rating for outdoor or damp locations.
- Interface and programming: USB, CAN, or RS485 interfaces enable parameter changes and data logging. Bilingual or multi-language displays can help in diverse teams.
- Reliability and protection: Look for clear fault display, over-current/short-circuit warnings, and robust protections to minimize downtime.
FAQ
- What is an ATS panel and why do I need one?
An ATS panel automatically transfers power between utilities and a generator to keep critical devices powered during outages, reducing manual switching and risk of back-feed.
- What should I check before buying an ATS panel?
Check voltage, phase, transfer time, fault indicators, and whether it supports one or multiple generators. Ensure compatibility with your generator controller.
- Is a higher-end panel always better?
Not always. Weigh needed features, ease of installation, and maintenance against cost. For simple setups, a basic dual-power ATS with clear faults may suffice.
- Can I install an ATS panel myself?
Yes, if you have electrical wiring experience and follow manufacturer instructions. For complex multi-generator systems, professional installation is advised.
- What maintenance does an ATS panel require?
Periodic visual inspection, verify wiring integrity, test automatic transfer function, and review fault logs or alarms to ensure readiness.
