Fast Acting Brake Rectifier 220V/380V Universal Fit
If you’re sourcing brake rectifiers for elevator systems or industrial lifting equipment, you already know how critical reliable braking performance is — a slow or failed brake response isn’t just a maintenance headache, it’s a safety liability.
This ZLD series electromagnetic brake rectifier module is built specifically for that job. It converts AC input (220V or 380V) into a stable DC output (99V or 170V) to drive electromagnetic brakes with fast, precise actuation. We manufacture these in-house in Shenzhen, using flame-retardant enclosures, epoxy resin potting, and high-grade polypropylene components — so what you’re getting isn’t a generic rectifier rebadged for elevator use. It’s designed from the ground up for braking applications.

What This Module Actually Does
Electromagnetic brakes on elevators and hoisting equipment need a DC power source to engage and release the brake coil. The problem with using raw rectified AC is the response is slow and the coil runs hotter than it needs to. This module solves that by delivering a fast-acting half-wave or full-wave rectified DC output tuned to the brake coil’s rated voltage — so the brake releases quickly when the elevator starts, and clamps down hard the moment power cuts.
From the image and specs, here’s what you’re working with:
- Compact black housing with mounting ears — DIN rail or panel mount ready
- 6-terminal screw block (green connector) for easy field wiring
- Clearly labeled polarity on terminals (−/+ markings on 1–6)
- Model label: ZLD-99V | AC220V → DC99V (170V version also available)
- Suitable for single-phase 220V or three-phase 380V input systems

Why Procurement Teams Choose This Over Generic Alternatives
Fast Brake Response — Fewer Callbacks, Safer Operation
The module is optimized for rapid coil energization and de-energization. In elevator maintenance, sluggish brake response leads to floor-level misalignment and wear on mechanical components. Fast actuation means your end-customers get smoother stops and your service teams spend less time on site.
Epoxy Resin Potted — Built for Real Installations
The internals are fully encapsulated in epoxy resin. That matters in elevator machine rooms where humidity, dust, and vibration are facts of life, not edge cases. Potted modules resist moisture ingress and handle vibration without component fatigue over time.
Flame-Retardant Housing
The enclosure uses flame-retardant plastic that meets international fire safety standards. For elevator system integrators and OEMs, this isn’t optional — it’s a specification requirement in most markets.
Polypropylene Capacitors — Better for the Environment, Better for Longevity
We use high-performance polypropylene film capacitors rather than older electrolytic types. They run cooler, last longer, and don’t contain the hazardous materials that cause headaches during RoHS compliance checks.
Universal Input Compatibility — One SKU Covers More Ground
The 220V and 380V versions cover the two most common elevator power supply configurations worldwide. Whether you’re supplying into the European market, Southeast Asia, or the Middle East, you’re not stocking half a dozen variants.
Simple Wiring, Reduced Installation Error
The 6-screw terminal block with clearly marked polarity (visible on the label) cuts installation time and reduces the risk of field wiring mistakes — which matters when you’re supplying to elevator maintenance contractors who are working fast.
Best Practice: Installation & Application Notes
Based on real-world deployment feedback from elevator OEMs and maintenance contractors:
- Match output voltage to coil rated voltage exactly. Running a 99V coil on 170V output — even briefly — will burn the coil. Always verify the brake coil nameplate before ordering.
- Use the 220V input version for single-phase control circuits, even in 380V three-phase elevator systems — the control cabinet typically has a 220V single-phase tap for accessories.
- Secure the module away from direct heat sources in the machine room. Epoxy potting gives excellent passive protection, but keeping ambient temps below 50°C extends service life significantly.
- Check terminal tightness during commissioning. Screw terminals can loosen slightly during transport. A quick re-torque before energizing prevents intermittent connection issues.
- For OEM integration, the bracket mounting ears allow direct panel mounting without additional hardware — saves assembly time on production lines.
FAQ — What B2B Buyers Ask Before Ordering
Can one model handle both 220V and 380V input?
No — the 220V and 380V versions are separate SKUs (ZLD-99V and ZLD-170V respectively). However, both are stocked and available. If you’re supplying to mixed markets, we recommend ordering both versions. We can discuss bundled pricing for mixed orders.
Q2: What’s the minimum order quantity, and do you offer OEM labeling?
MOQ is flexible depending on your sourcing volume — we work with both project-based buyers and distributors. OEM labeling and custom packaging are available. Contact us with your expected annual volume for a tailored quotation.
Do these meet international safety certifications (CE, RoHS)?
Our modules are manufactured with RoHS-compliant materials. CE documentation is available for qualified buyers. If you have specific market certification requirements, let us know early in the inquiry so we can provide the appropriate compliance documentation.
What’s the typical service life, and is there a warranty?
Under normal operating conditions (proper voltage match, ambient temp within spec), these modules routinely exceed 5 years of continuous service. We offer a standard manufacturer warranty, and for volume buyers, we can discuss extended warranty terms. The epoxy potting and polypropylene capacitors are specifically chosen to minimize early failure rates.
How do I know if this is compatible with my elevator brand/model?
Compatibility is determined by your brake coil’s rated DC voltage and your control circuit’s AC supply voltage — not by elevator brand. If your brake coil is rated DC 99V and your control supply is AC 220V, the ZLD-99V is your module. We’re happy to review your existing brake specs if you share the nameplate data — our technical team can confirm compatibility before you commit to an order.
