NOTE | ||
1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1μ & 47μ parallel capacitor. 3 .Tolerance: includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 5 . Derating may be needed under low input voltages. Please check the derating curve for more details. | ||

This remote support not only saves time and resources but also ensures a seamless experience for customers using the NDR-240.
When the voltage regulation control circuit inside the power supply malfunctions, issues such as damaged or degraded components—including sampling resistors, error amplifiers, optocouplers, or power control chips—can occur. These faults may cause the output voltage to become excessively high or low.
The aging, failure, or reduced capacity of filter capacitors can increase the ripple component in the DC voltage output by the power supply. This may disrupt the normal operation of connected load equipment.
If the guide rail power supply's installation dimensions do not align with the equipment’s guide rail, or if it is improperly secured during installation, the power supply may not be firmly fixed. This can compromise both the safety and stability of the system.
