SWF ESD141 Kone Brake Rectifier Module 60003098

SWF · ESD141 Series · Brake Rectifier · 200-690VAC 50/60Hz · Kone OEM P/N 60003098

The SWF ESD141 brake rectifier module (Kone spare part 60003098) is an industrial-grade AC-to-DC power converter built for the spring-set / electrically-released DC brake coil on Kone elevator traction machines. Originally engineered by SWF Krantechnik (Germany, now part of Kone), the ESD141 accepts a wide 200-690V AC, 50/60Hz machine-room supply and delivers a controlled half-wave / full-wave DC output to release the brake during run, with a fast cut-off to set the spring-applied brake on stop. KOEED stocks the genuine ESD141 / 60003098 for service replacement in legacy and current Kone elevator systems worldwide.

This page is the technical reference for maintenance engineers, system integrators and service companies that need to identify, source and swap a failed brake rectifier on Kone MonoSpace, MiniSpace, EcoSpace and N MonoSpace installations. The ESD141 family is also deployed on gearless, geared, MRL (machine-room-less) and hydraulic elevator systems as the OEM-specified rectifier for the machine brake coil. Send the elevator model and the existing rectifier marking to Moritta@KOEED.COM and we will confirm stock and lead time within 24 hours.

1. Key Technical Specifications

The SWF ESD141 / 60003098 is a wide-input industrial brake rectifier optimized for the inductive DC brake coils used on Kone elevator machines. The specifications below are taken from the SWF / Kone datasheet family for the ESD141 series.

2. Application Scenarios — Where It Fits

The ESD141 / 60003098 is the OEM-referenced brake rectifier for Kone elevator systems. It is typically installed wherever a Kone MonoSpace, MiniSpace, EcoSpace or N MonoSpace traction machine uses a spring-set, electrically-released DC brake. KOEED also supports broader elevator spare-parts sourcing for the same call-out, including monitoring electronics, door drives and overspeed governors.

• Kone MonoSpace 500 — gearless MRL elevator machine; ESD141 fitted inside the motor housing or cabinet as the brake-coil rectifier.
• Kone MiniSpace — small machine-room geared / gearless elevator; ESD141 used on the disc-brake / drum-brake coil.
• Kone EcoSpace — compact MRL platform for low-to-mid rise buildings; ESD141 paired with the EcoSpace-spec motor brake.
• Kone N MonoSpace — next-generation MonoSpace family; ESD141 specified for the upgraded brake module.
• Hydraulic elevator retrofits — ESD141 sometimes used as a controlled DC supply for the brake / valve actuator on Kone hydraulic conversions.
• Industrial hoist / crane brake retrofits — SWF ESD141 was originally designed for hoist and crane duty; ESD141 still appears on industrial retrofit specs where 200-690V AC is available.
• SWF family cross-reference — ESD111, ESD211 and ESD141-A live in the same SWF brake-rectifier family. Check coil current and input voltage range before substitution.

For multi-elevator service fleets, KOEED can quote the ESD141 alongside monitoring electronics, a Siemens S7 PLC that runs the elevator group controller, a Schneider Modicon safety relay, a Mitsubishi MR-J4 servo spare, or an Omron E3S photoelectric sensor for the same elevator service BOM.

3. Integration & Wiring Notes

Because the SWF ESD141 sits on the safety path of an elevator drive, the wiring, grounding and switching logic must follow the original Kone schematic. The notes below summarize the integration points that field engineers most often ask KOEED about when planning a 60003098 swap-out.

• AC supply (L / N or L1 / L2): Connect the 200-690V AC feed from the machine-room supply to the ESD141 input terminals. Polarity is non-critical on single-phase AC; verify the input range covers the actual line voltage (e.g. 400V AC in EU sites, 480V AC in North America, 600V AC on some industrial mains).
• DC output to brake coil: The DC output goes to the spring-applied brake coil on the Kone traction machine. Observe polarity markings on the rectifier — reverse polarity will not release the brake.
• Coil suppression: The ESD141 includes internal clamping for the brake-coil inductive kick. Do not add a free-wheeling diode directly across the coil; that prevents the fast cut-off required for the safety stop.
• Control / enable: The brake release is typically driven from the elevator controller's safety relay chain. Make sure the ESD141 sees the enable signal through a dedicated contactor, not a PLC output that can chatter under fault conditions.
• Grounding: Bond the ESD141 chassis / DIN-rail ground to the cabinet protective earth. The rectifier heatsink should be grounded even on insulated-mount variants.
• Adjacent automation: Many Kone elevator cabinets co-locate an Allen-Bradley CompactLogix or Siemens SIMATIC S7-300 controller with the ESD141. Route the ESD141 wiring harness away from 24V DC control bundles to avoid coupling noise into analog tacho feedback.
• Cross-brand controller pairings: ESD141 is controller-agnostic. KOEED commonly ships the 60003098 next to a Yaskawa Sigma-7 servo spare, a Panasonic FP PLC, or a Fanuc spindle-drive part in mixed-vendor service kits.
• Sensing and feedback: If the elevator uses a KEYENCE LV-N11N laser sensor or a KEYENCE FS-N18N fiber sensor for door-zone / level feedback, run those signals on shielded twisted pair and keep the ESD141 power on a separate breaker.

4. Installation & Commissioning Tips

Use the checklist below whenever an ESD141 / 60003098 is being installed in the field. The ESD141 itself is a passive-replacement module, but the surrounding safety chain is what makes the elevator pass inspection.

• De-energize and lock-out the machine-room supply, the drive DC bus, and the safety circuit before touching the ESD141 terminals. Verify zero energy with a meter on the AC input and the brake-coil leads.
• Visually inspect the existing ESD141 for bulging, burned solder joints, cracked housing, or discoloration around the AC input terminals — all classic signs of a failed brake rectifier.
• Match the replacement by part number (60003098) and the printed ESD141 series marking. Do not substitute a generic bridge rectifier; the controlled DC output profile is what releases the brake smoothly.
• Torque the terminals to the values shown on the ESD141 datasheet label. Loose AC input terminals are the #1 cause of repeated ESD141 failures under elevator inrush current.
• Verify input voltage on the cabinet feeder before first power-up. ESD141 covers 200-690V AC, but the brake-coil DC rating must match the elevator's brake specification — do not over-volt a 110V DC coil from a 690V AC feed.
• Function-test the brake from the controller: command brake release, measure DC voltage at the coil, command brake set, confirm the brake sets within the time specified in the Kone service manual.
• Run a controlled empty-car test before returning the elevator to service: floor-by-floor run, observation of brake noise, brake-pickup timing, and emergency stop from the controller.
• Document the swap with a brief service note (date, technician, ESD141 S/N, input voltage measured, brake DC measured) and file it in the elevator log book.
• For recurring ESD141 trips, the cause is usually upstream — contactor chatter, coil insulation breakdown, or a controller that re-energizes the ESD141 too quickly after a stop. KOEED can help with AI-driven fault diagnosis if you send the symptom log.
