Typical applications

How to specify the right NES Series

  1. Size the contact rating for the inductive load, not just the resistive current (AC-3 duty for motors)
  2. Check the coil voltage and frequency available in the panel: 24 V DC, 110 V, 230 V or 400 V AC
  3. Confirm the auxiliary contact count needed for the control and indication circuit
  4. Match the enclosure rating to the environment (IP20 inside a panel, IP65 on the machine)

NOTE

1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.

2.Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1 uf & 47uf parallel capacitor.

3.Tolerance : includes set up tolerance, line regulation and load regulation.

4.Line regulation is measured from low line to high line at rated load.

5.Load regulation is measured from 0% to 100% rated load.

6.For the request of GB4943.1 ,the power supply is only suitable for use in the altitude 2000m below and the non tropical climate condition.

7.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. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”


Frequently asked questions about the NES SERIES POWER SUPPLY NES-25W

What is the difference between a contactor and a relay?

A contactor is built for switching power circuits repeatedly at high current, often with motor duty ratings (AC-3) and arc-suppressing chambers. A relay switches control signals at low current. In practice: contactor for the motor, relay in the control circuit that drives the contactor coil.

How do I calculate the correct contactor size for a motor?

Use the motor's full-load current, apply the AC-3 rating for the operating voltage, and allow for the number of starts per hour. As a rule of thumb, the contactor's AC-3 rating should be at least equal to the motor FLC, then step up one frame if the duty is heavy.

Do you supply the coil voltage I need?

Coil voltages are specified per order. Send the model number, coil voltage and frequency you require and we will confirm availability and lead time.

Are auxiliary contacts included?

Base models come with the standard auxiliary contact configuration for that frame. Add-on auxiliary blocks and mechanical interlocks can be quoted with the contactor.
