Product Information

Product Overview

The RX20 wirewound power resistor converts electrical energy into heat in power supplies, braking networks, discharge circuits and industrial test loads. The correct rating depends on continuous power, pulse energy, duty cycle, airflow and mounting.

Typical Applications

Industrial power supplies and converters
VFD braking and discharge circuits
Load banks and test equipment
Power control and electronic equipment

Selection Guidance

Please provide target resistance, continuous and pulse power, duty cycle, mounting space, cooling conditions and required tolerance. LORIDA will confirm the suitable model, dimensions and terminal arrangement.

RFQ Information

Send the requested RX20 rating, resistance, tolerance, quantity and application conditions. Specifications shown here describe represented source options and do not replace final datasheet or sample approval.

FAQ

Can the listed power ratings be interchanged?

No. Select the rating and physical construction against actual thermal and pulse conditions.

Are custom resistance values available?

Resistance availability depends on power, body size and winding design. Confirm the exact combination before ordering.
