Lenze 8211RH-1A — 8200 Vector Power Supply Module (1 A, Regel-Hochlauf)

LENZE · 8200 VECTOR · POWER SUPPLY MODULE · IN STOCK

The Lenze 8211RH-1A is a 1 A line-side power supply module from the Lenze 8200 Vector drive family. It generates the 320 V DC bus for the inverter section, the 24 V control voltage for the controller card, and the line-side monitoring for undervoltage, overvoltage, phase-loss and current limit. The RH suffix marks the Regel-Hochlauf (controlled ramp) variant used wherever soft bus charging and predictable pre-charge behaviour are required.

In a mixed-vendor cabinet the supply module is often the part that fails first — surge events, phase-loss trips and aged electrolytics all take their toll. KOEED keeps the 8211RH-1A on the shelf for the Lenze 8200 Vector, 8200 motec and 8200 servo drive lines so a single email can replace a failed module and put a line back into production. Quote requests are answered within 24 hours at Moritta@KOEED.COM.

1. Key Technical Specifications

The 8211RH-1A is the dedicated 1 A supply for the Lenze 8200 Vector inverter chassis. The “1A” suffix denotes the 1 A continuous output current rating; the “RH” denotes the German Regel-Hochlauf controlled ramp / pre-charge variant. Always cross-check the rating plate against the existing supply module before fitting a spare — the 8211 family also includes higher-current siblings used on larger drives in the same family.

Specifications above are sourced from the Lenze 8200 Vector system manual and our bench inspection of incoming 8211RH-1A stock. For firmware-level configuration, always refer to the official Lenze datasheet revision for your drive.

2. Application Scenarios — Where It Fits

The 8211RH-1A is a service / replacement part, so its “application” is really “any cabinet that already runs a Lenze 8200 Vector drive”. Across our customer base we see it most often in:

• Conveyor and material-handling lines — where a single failed supply module takes out a whole section of line until a hot-spare is fitted.
• Mixers, agitators and extruders — 8200 Vector drives are common in plastics, food & beverage and chemical factory automation cells, often alongside Siemens SIMATIC PLCs for the supervisory layer.
• Pumps and fans — HVAC, water-treatment and process-air skids using 8200 motec decentralised drives.
• Machine tools and hoists — 8200 servo installations where the supply module is shared between an inverter and a servo axis.
• Printing and packaging machinery — long-life European machines that often mix Lenze drives with Allen-Bradley ControlLogix or Omron SYSMAC controllers.

If the line also uses Mitsubishi MELSEC CPUs, Fanuc CNC boards, Schneider Modicon I/O, Yaskawa Σ-7 servos, Panasonic FP PLCs, or KEYENCE vision systems, send the full BOM in one email and KOEED will quote the whole stack from a single inbox.

3. Integration & Wiring Notes

A 8200 Vector supply module is on the line side of the drive, so almost every terminal block in the cabinet touches it. The points below are the ones that bite engineers in practice.

• Line-side wiring. The 3-phase mains enters the supply module first and is then bridged to the inverter section. Loose terminal screws on the line block are the most common cause of “supply module” trips that are actually wiring problems.
• DC-bus link. The 8211RH-1A charges the internal bus to ~320 V DC before the inverter section is enabled. The RH controlled ramp limits the inrush, which matters on weak mains or generator supplies.
• 24 V control rail. The 24 V output feeds the controller card, any KEYENCE vision head, and the field-side encoder wiring. If the 24 V drops, the drive will fault on “control undervoltage” even when the bus is healthy.
• Phase-loss detection. The supply module monitors all three phases. A single lost phase on a regenerative load can damage the bus capacitors before the inverter trips — fit input reactors upstream if the supply is known to be unstable.
• Fieldbus & option cards. Communication modules (PROFIBUS, INTERBUS, CAN, EtherNet/IP gateways) plug into the 8200 Vector control card, not the supply module, but they pull their 24 V from the supply module’s auxiliary rail. Plan slack on that rail when you fit Yaskawa Σ-V or Schneider Lexium option cards.
• EMC and grounding. Keep the PE bond between the supply module chassis and the cabinet back-plate short and flat. Long pigtails defeat the line filter and push the drive over its EMC limits.

4. Installation & Commissioning Tips

Most “the new module doesn’t work” tickets on 8200 Vector drives come from a handful of preventable causes. Run through this list before powering up.

1. Isolate and verify dead. Lock-out / tag-out the upstream breaker or contactor and measure the DC bus with a known-good meter. The 8211RH-1A’s bus capacitors hold charge for several minutes after mains removal.
2. Match the variant. Confirm the suffix — 1A vs 2A, RH vs standard — matches the rating plate on the host drive. The connectors are keyed, but a higher-current supply on a lower-rated drive does not give you more headroom; it just changes the protection curve.
3. Re-torque the line terminals. Thermal cycling loosens screw terminals over years. A re-torque to the Lenze-specified value (Nm printed on the terminal block) is a free win.
4. Inspect the bus capacitors. If the old supply module failed with a swollen case or burnt smell, check the bus caps on the inverter section too. A shorted cap will destroy a new supply module within minutes.
5. First power-up with no motor. Bring the drive up with the motor disconnected and the enable input open. Watch the DC-bus voltage settle and the 24 V rail come up before applying enable.
6. Re-load parameters from the controller card. The supply module itself is largely transparent to the parameter set, but the drive may have logged a trip history that needs clearing. Use the PLC error code database if a trip code does not match the manual.
7. Log the swap. Stamp the date and serial of the new module on the cabinet drawing. A 8200 Vector line that has had two supply-module swaps in five years usually has an upstream power-quality issue worth chasing.

For cabinet-level signal work, the PLC analog calculator and Modbus CRC calculator are useful when the drive’s analogue setpoint or comms link has to be re-validated after the swap.
