KZL1-170-4 Bremsgleichrichtermodul Industriemotorteil
If you’re sourcing brake rectifiers for industrial motor applications, you already know how critical reliable braking performance is to your equipment’s safety and longevity. This KZL1-170-4 Brake Rectifier Module is built specifically for that demand — converting 380V AC input to a stable 170V DC output to power electromagnetic brake coils on three-phase induction motors.
We manufacture this unit in-house, so we control every step — from winding the copper coils to final QC inspection. No middlemen, no quality surprises.
Was dieses Modul tatsächlich bewirkt
This rectifier sits between your motor control circuit and the brake coil. When the motor stops, the rectifier supplies DC power to energize or de-energize the electromagnetic brake — achieving fast, controlled stopping. It’s widely used in:
- Brückenkräne und Hebezeuge — where load-holding safety is non-negotiable
- Verpackungs- und Förderlinien — precise stop positioning matters
- CNC-Werkzeugmaschinen — spindle and axis brake control
- Elevators & lifting equipment — certified braking response required
- Industrielüfter und Kompressoren — controlled deceleration to reduce mechanical wear

Why Buyers Keep Coming Back to Us
✅ Pure Copper Leads — Not Aluminum, Not Mixed
Wir verwenden 100% reiner Kupferdraht on every unit. It handles heat better, resists oxidation, and maintains conductivity over years of use. Aluminum or copper-clad wire is a common cost-cutting move in this category — we don’t do that.
✅ Premium PBT Housing
The shell is molded from high-grade PBT (Polybutylene Terephthalate) — the same material used in automotive electrical components. It holds up against heat, humidity, and industrial chemicals far better than standard nylon or ABS housings. You’ll see it in the photo — the color is consistent, the edges are clean, no sink marks.
✅ Two Circuit Types Available
- Diodentyp: Simple, cost-effective, proven for standard braking cycles
- MOSFET (FET)-Typ: Faster switching response, lower heat generation, ideal for high-frequency braking applications
✅ Fast-Brake Option for Demanding Applications
Das fast-response version uses a half-wave + freewheeling circuit design that significantly reduces brake release/engage lag. In crane or hoist applications, this translates directly to safer, more predictable load control.
✅ Factory Direct — We Make It
From the image, you can see the SNXRON brand label with batch number and QC stamp right on the unit. That’s our own production. We’re not trading — we’re manufacturing. MOQ is flexible, and we can do OEM labeling for buyers who need their own brand on the product.
Best Practices from Field Experience
After years of supplying these modules to crane manufacturers, machine tool plants, and conveyor system builders, here’s what we’ve learned:
1. Match the rectifier output to your brake coil rating. A 170VDC rectifier paired with a coil rated for 99VDC will burn the coil. Always confirm your brake nameplate voltage before ordering. We stock both 99V and 170V versions — just ask.
2. Fast-type isn’t always better. For light-duty applications with infrequent stops, standard diode-type units last longer and cost less. Fast-type excels in high-cycle environments (>20 stops/hour).
3. Check your wiring before blaming the rectifier. Most field failures trace back to reversed polarity on DC output or loose AC input connections. The color-coded leads on our units (red/black clearly marked) help reduce installation errors significantly.
4. Keep it dry during installation. PBT housing is moisture-resistant, not waterproof. For outdoor or wet environments, mount inside an IP65 enclosure.
5. Buy with some buffer stock. These are wear components in high-cycle systems. Having 10–20% spare inventory on hand prevents production line downtime. We support blanket orders with staged delivery.
Häufig gestellte Fragen
Can we get OEM branding or custom labeling on the units?
Yes. We support private label / OEM. Minimum quantities apply — contact us for details. Lead time for branded versions is typically 7–15 days depending on order size.
What’s the difference between the diode type and MOSFET type — which one should we order?
Diode type is cost-efficient and suitable for standard braking cycles (fewer than 20 stops/hour). MOSFET type offers faster brake response and lower thermal output — recommended for cranes, hoists, or any application with frequent stopping cycles or where braking speed is safety-critical.
Wie hoch ist Ihre Mindestbestellmenge und Lieferzeit für Großbestellungen?
MOQ is flexible for standard models — we can discuss based on your volume. Stock items typically ship within 3–5 business days. Custom voltage or configuration orders: 10–20 days. We welcome long-term supply agreements.
Do these units carry any certifications?
Each unit passes our internal QC inspection (batch number and inspection stamp visible on label). We can provide test reports on request. CE documentation is available for applicable export markets — please specify your destination market when inquiring.
Can you supply other voltage configurations — like 99V output or 220V input?
Absolutely. We manufacture across a range of input/output combinations. The ZLKS-99-4 (220V input / 99V DC output) is shown right alongside the 170V version in our product images. Tell us your motor brake specs and we’ll match the right unit.
