Product Introduction

Honeywell CW4500 is a Calcoil power module used in industrial induction-heating equipment, particularly heating systems associated with paper coating, laminating, and calendering processes. Current equipment records identify it as a three-phase 208/220 VAC power module using an IGBT power stage, with the associated Calcoil component number 6560010028.

The unit is not a conventional PLC power supply. It belongs to the Calcoil heating architecture and delivers power to an induction-heating zone. One commercial technical record lists the unit at approximately 4.08 kg, while another identifies 4,500 W output and a 20 A current figure; because published specifications vary between aftermarket sources, the exact electrical rating should be confirmed from the nameplate and machine documentation before purchase.

Key Technical Specifications

Radwell identifies CW4500 as a Calcoil power module, specifies 208/220 VAC three-phase input, and lists a 9 lb weight. Another supplier identifies 4,500 W output and 20 A, but those figures should be treated as supplier data rather than a confirmed Honeywell datasheet specification.

Application and Selection Notes

This unit belongs to a specialized heating system.

In Calcoil installations, the power module controls an induction-heating zone rather than supplying ordinary instrumentation or controller loads. One field listing specifically associates the 4500 W version with Calcoil Model 9710 calender roll heating systems, where multiple modules can be combined to distribute heating power across different zones.

That distinction matters when sourcing a spare. A similarly rated three-phase IGBT converter is not automatically interchangeable. The cabinet wiring, heating coil, control interface, zone address, and machine configuration all need to match.

For procurement, I would record the CW4500 nameplate, serial number, voltage, current/output rating, and any zone-identification information before removing the original unit. This is one of those cases where a ten-second photo can prevent a much longer commissioning problem.

Advantages and Limitations

Advantages

• Designed specifically for Calcoil induction-heating equipment.
• Three-phase 208/220 VAC input architecture.
• IGBT-based power conversion.
• Suitable for zoned heating applications.
• Useful as a maintenance spare for established Honeywell Calcoil systems.

Limitations

• Legacy equipment with limited public technical documentation.
• Not a generic industrial power supply.
• Exact output rating should be confirmed from the installed unit.
• Compatibility depends on the complete Calcoil heating system.

Quality Inspection and Pre-Shipment Checks

1. Incoming inspection: Verify Honeywell markings, CW4500 identification, component number where present, serial number, terminal condition, housing integrity, and signs of overheating or previous repair.
2. Live test: Use an appropriate Calcoil-compatible test arrangement to verify power-up, status indication, control response, and heating-power output. Record the results in a Test Report.
3. Electrical checks: Inspect power terminals, grounding continuity, insulation condition, and IGBT/power-stage condition according to the approved test procedure.
4. Configuration verification: Record zone information, wiring arrangement, control settings, and nameplate data before shipment.
5. Final QC: Photograph the identification label, protect the power module against ESD and impact, use rigid cushioning, and retain the QC record.

Where available, test photographs and the Test Report should accompany the shipment.

Technical Replacement Risks

Input voltage mismatch. Public records identify 208/220 VAC three-phase input. Do not connect the unit to a 380/400 VAC supply without confirming the actual machine architecture and required voltage conversion.

Output-rating mismatch. “4500” is commonly interpreted as the power class, but supplier specifications are not fully consistent. Match the nameplate and machine documentation rather than relying on the model number alone.

IGBT damage. Induction-heating modules switch substantial power. Incorrect load connection, phase problems, poor cooling, or insulation faults can damage the power stage.

Cooling problems. Dust and blocked airflow can raise semiconductor temperature. Inspect cabinet ventilation and heat-transfer surfaces before fitting the replacement.

Zone configuration. When several heating modules are installed, the replacement must be associated with the correct zone and control wiring.

One old-maintenance rule applies here: do not assume “same model” means “same configured installation.” Verify the electrical and machine-side details before energizing.

Purchase and Logistics Notes

For international procurement, use a description such as Honeywell CW4500 Calcoil Induction Heating Power Module, 208/220 VAC, 3-Phase. Where present, include associated component number 6560010028.

The purchase order should clearly state the actual product condition:

• New Original
• New Surplus
• Refurbished
• Repaired

Request confirmation of the nameplate data, functional test status, hardware condition, warranty, country of origin, gross weight, and package dimensions.

Current industrial suppliers list the item as available in new, unused, or refurbished conditions, while Radwell identifies it as discontinued by the manufacturer. Availability therefore needs to be confirmed for each transaction rather than assumed.

For export packing, protect the power terminals and housing against impact, use moisture protection where appropriate, and keep the commercial invoice, packing list, and product label consistent.

Quick Conclusion

• CW4500 is a Honeywell Calcoil induction-heating power module.
• Public records identify 208/220 VAC, three-phase input and an IGBT power stage.
• The unit is associated with Calcoil heating systems, including calender-roll applications.
• The commonly associated component number is 6560010028.
• Output specifications vary among aftermarket listings, so the actual nameplate and machine documentation should control the replacement decision.
• Current commercial records classify the product as a legacy/discontinued spare, making exact identification important.

FAQ

What is the Honeywell CW4500?

It is a Calcoil induction-heating power module used in industrial heating equipment, particularly systems associated with paper-processing and calendering applications.

What input voltage does it use?

Current industrial records identify 208/220 VAC, three-phase input.

Is CW4500 a PLC or DCS power supply?

No. It is a dedicated Calcoil heating power module, not a conventional control-system power supply.

What is the associated component number?

Commercial technical records associate CW4500 with 6560010028

What is the output power?

Several aftermarket records identify it as a 4,500 W class unit, with one supplier listing 20 A. Because these figures are not consistently documented across sources, verify the original nameplate before ordering.

What should be checked before replacement?

Confirm the complete model, nameplate voltage, output rating, zone configuration, wiring, cooling arrangement, and machine controller interface. For a legacy Calcoil system, the complete application configuration matters just as much as the part number.
