Compatible Replacement & Equivalent Models
The following models are commonly evaluated as functional replacements or equivalents for the SCS UFS-22. Always verify electrical and mechanical compatibility before substitution:
- SCS UFS-20 – Lower-rated variant in the same UFS series; verify braking capacity
- SCS UFS-25 – Higher-rated variant; drop-in compatible in most installations
- Generic UFS-22 Compatible Units – Third-party braking units matching the UFS-22 form factor and electrical spec; confirm resistance range and duty cycle
- OEM-Equivalent Braking Modules – Contact Konmask for cross-reference to Siemens, ABB, or Schneider equivalents where applicable
Important: Substitution must be validated against the host drive’s braking resistor requirements. Incorrect selection may cause drive faults or equipment damage.

Typical Applications
- Variable frequency drive (VFD) braking circuits requiring rapid deceleration
- Crane and hoist control systems with regenerative braking demands
- Conveyor and material-handling lines with frequent start/stop cycles
- Elevator drive systems requiring smooth, controlled stopping
- CNC machine tool spindle drives and servo axis braking
- Pump and fan applications with high-inertia loads
System Compatibility
The SCS UFS-22 braking unit is intended for integration with compatible SCS drive platforms. Before installation, confirm the following:
- Host drive DC bus voltage rating matches the UFS-22 input specification
- Braking resistor (external) resistance and wattage are within the UFS-22 operating range
- Control wiring and enable signal logic are compatible with the host drive’s braking interface
- Enclosure thermal management is adequate for the braking duty cycle
Contact our engineering team for system-level compatibility review at no charge.
Selection Guide
Use the following criteria to confirm the UFS-22 is the correct choice for your application:
- Step 1 – Identify host drive model: Confirm the SCS drive model number and its braking unit interface specification.
- Step 2 – Determine braking duty: Calculate peak braking power and duty cycle (e.g., 10% ED, 40% ED) based on load inertia and deceleration time.
- Step 3 – Verify DC bus voltage: Match the UFS-22 voltage rating to the drive’s DC bus level.
- Step 4 – Select external resistor: Choose a braking resistor with resistance and wattage within the UFS-22’s permissible range.
- Step 5 – Confirm form factor: Verify mounting dimensions and terminal layout against your panel design.

Replacement & Compatibility FAQ
Q: Can I use a third-party braking unit instead of the SCS UFS-22?
A: Yes, provided the replacement unit matches the DC bus voltage rating, braking resistance range, and duty cycle of the UFS-22. We recommend verifying with the host drive manufacturer before substitution.
Q: Is the UFS-22 compatible with non-SCS drives?
A: Potentially, if the drive’s braking interface and DC bus voltage are compatible. Contact our team with your drive model for a compatibility assessment.
Q: What external braking resistor should I use with the UFS-22?
A: The resistor selection depends on the required braking torque, duty cycle, and DC bus voltage. Share your application parameters and we will recommend a suitable resistor.
Q: Do you supply the braking resistor separately?
A: Yes. Contact us with your specifications and we can source a matched braking resistor alongside the UFS-22.
Q: What is the warranty on the SCS UFS-22?
A: We offer a 12-month warranty against manufacturing defects on all genuine SCS components supplied by Konmask. Terms and conditions apply.
