The low-temperature chamber power supply operates on 380V voltage. While the manufacturer recommends using a dedicated, open connection for safety, some users may not have the space to do so due to site limitations and might opt for a standard socket instead. However, there are several important considerations when doing this—many of which are small but critical details that users often overlook. According to YASELINE’s low-temperature chamber experts, it's crucial not to plug or unplug the device at random during operation. Here's why:
When the low-temperature chamber is running normally, the internal temperature drops to a set point, and the temperature controller automatically cuts off the power. At this moment, the refrigerant pressure inside the system is already low, which makes it easier for the motor to start up under normal conditions. If the power is forcibly disconnected and then immediately reconnected while the refrigerant is still under high pressure, the sudden surge in voltage can cause the motor to experience excessive load. This can lead to a starting current that is 20 to 30 times higher than usual, potentially causing the motor to overheat and burn out.
To avoid this risk, it's important to wait at least 3 minutes after turning off the power before reconnecting. This allows the high and low-pressure sides of the refrigeration system to equalize, ensuring a safer and more stable restart. Always follow these guidelines to protect your equipment and ensure long-term performance.
