Full catalogue description: AC DC 1000W Digital Screen UPS Switching Power Supply Adjustable SMPS with External Control

Typical applications

Motor control centres and pump or fan starters
Machine building, conveyors, packaging and CNC equipment
HVAC control panels and building automation
Water treatment, irrigation and pumping stations
Panel retrofits replacing electromechanical control gear

How to specify the right Adjustable Display Series

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

Remark 1. All parameters are measured at 230VAC input voltage, rated load and 25ºC unless otherwise specified.
2. Ripple and noise voltage are measured with a 20MHz bandwidth oscilloscope with 0.1μ and 47μ capacitors added to the end of a 12-inch twisted pair, and measured at 20MHZ bandwidth.
3. Accuracy: includes setting error, linear regulation rate and load regulation rate.
4. Output must be derated in low input voltage conditions, please refer to the static characteristic curve for details.
5. Startup time is measured under cold start, and frequent switching may increase the startup time."

Q: 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.

Q: 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.

Q: 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.

Q: 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.
