FAQs

RL vs RLW - Which reactor suits my application? ▼

RL Reactors perform better with regard to watts loss and overload capability:

  • 150% Continuous Service Factor up to 750A
  • Available in open style, NEMA 1/2 and NEMA 3R cabinets
  • No de-rating needed for load side applications

RLW Reactors features:

  • Continuous Service Factor is 100%
  • Require de-rating for load side applications
  • Available in open or NEMA 1/2

Both are stocked in various sizes and enclosure options @ Vanco.

Should I use a 3% or 5% Reactor? ▼

3% Reactors:

  • Ideal for absorbing line spikes and motor current surges
  • Prevent nuisance tripping in most applications
  • Typically specified by most drive manufacturers
  • THID: 45% or less when used alone

5% Reactors:

  • Better for reducing harmonic current and frequencies
  • Recommended for lowering VFD-generated harmonics
  • Reduce motor operating temperature
  • THID: 35% or less when used alone

Combination Benefits:

  • 3% AC + 3% DC: 33% or less THID
  • 5% AC + 3% DC: 28% or less THID
What are common mode current, peak voltage, and rise time? ▼
  • Common Mode Current: Induced by PWM drives, it flows through motor bearings, causing pitting ("fluting") and premature failure.
  • Peak Voltage: The highest voltage in a waveform, stressing motor insulation. Non-inverter motors handle ≤1,000V; inverter-duty motors handle higher (e.g., 1,782V for 575V motors).
  • Rise Time: Time for voltage to reach its peak. Faster rise times (e.g., <2μs for non-inverter motors) increase insulation stress.
How do I size MTE filters? ▼

Match the filter to the drive/motor voltage and current ratings. If an exact current match isn’t available, choose the next largest rating.

Where should filters be installed? ▼

Mount as close to the VFD output as possible to protect motor leads and the motor itself.

What are the warranty terms? ▼

All MTE filters (SineWave Nexus™, dV E-Series, dV Sentry™) include a 3-year warranty from shipment date.

Can I run multiple motors on one filter? ▼

Yes: SineWave Nexus™ (sum motor loads; separate overload protection required).

No: dV E-Series and dV Sentry™ (use SineWave Guardian™ for multiple motors).

What cable lengths are supported? ▼
  • SineWave Nexus™/Guardian™: Up to 15,000 ft.
  • dV E-Series/Sentry™: Up to 1,000 ft.
Do I need VFD-rated cables? ▼
  • SineWave Nexus™: No—standard cables are sufficient.
  • dV Series: Follow standard VFD guidelines.
Are isolation transformers required? ▼
  • SineWave Nexus™: Eliminates need for non-step-up transformers.
  • Step-up transformers: Use SineWave Guardian™ for differential mode issues.
What enclosures are available? ▼

NEMA 1/2 (indoor) and NEMA 3R (outdoor) options for all filters.

Do filters include safety features? ▼
  • Temperature Switches: SineWave Nexus™ and dV Sentry™ include 150°C thermal switches.
  • Overload Protection: All filters support 150% current for 1 minute and 200% for 10 seconds.
Are MTE filters certified? ▼

Yes—all are UL/cUL Listed and CE marked.

How does carrier frequency affect performance? ▼

Lower frequencies reduce drive/motor stress and heat loss. Optimal performance:

  • SineWave Nexus™: 4 kHz (operates 2–8 kHz)
  • dV Series: Lower frequencies recommended
