Functionality

An automatic rotary switch with one input and six outputs, specifically designed to safely and efficiently switch extremely high currents and voltages with minimal loss, allowing a single high-power source to serve multiple DUTs in sequence.

1. High-Power Multiplexing (16 MUX)

2. High Current / High Voltage Switching

3.Extremely Low Conduction Loss

4.Automated Sequential Control

5.Safe and Reliable Electrical Isolation

6.High-Current Dedicated Interfaces

Key Features

1. Automatically switch a single high-power resource (such as power supply, electronic load) to up to 6 different test devices, achieving multi-purpose utilization of a single source.
2. Support continuous current switching of 60A or above (some models can reach 100A+), and support high-voltage switching of hundreds of volts DC/AC (such as 400V, 1000V).
3. Low contact resistance: The contact resistance of relays is usually ≤ 0.5mΩ, and can even reach ≤ 0.1mΩ.
4. Programmed switching: Support automatic channel switching according to preset programs via LXI (Ethernet), GPIB or RS-232 interfaces.
5. Channel isolation: Each output channel is isolated from each other to prevent mutual influence when the tested equipment fails.
6. Connection method: Use large current terminals, bolt terminals or Anderson connectors to ensure a secure connection and eliminate loosening and overheating.

FAQ

Q:What is the maximum current this module can handle?

A: The standard version supports 60A continuous current, and can be customized for 100A, 200A, or even higher based on requirements.

Q:Does it generate excessive heat during switching? Will it burn out?

A: No, it won't. With contact resistance ≤0.5mΩ (as low as 0.1mΩ), power dissipation per channel at 60A is only about 1.8W. Combined with dedicated thermal design, it ensures stable long-term operation.

Q:What does "1.6-channel" mean? Is it 1 input and 6 outputs?

A: Yes, exactly. 1 common input channel (connect to power supply/load) and 6 branch output channels (connect to DUTs), allowing one power supply to sequentially serve six devices.

Q:Does it support automated control? How do I program it?

A: Yes, it does. Standard LXI (Ethernet) interface, with optional GPIB and RS-232. Provides IVI drivers, supporting LabVIEW, Python, C++, and other programming environments.

Q:Can I use it in my existing aging test system?

A: Yes, you can. Standard communication interfaces and protocols allow quick integration into existing systems. Custom protocols are also available upon request.
