Industrial Signal Filtering Solution – HITACHI LPF200A | AC Drive Low Pass Filter Board
Where This Product Is Used
The HITACHI LPF200A Low Pass Filter Board is engineered for integration into HITACHI AC drive and inverter systems where signal integrity and electromagnetic noise suppression are critical. Typical deployment environments include:
- Manufacturing & Process Automation – Installed in variable frequency drive (VFD) panels controlling conveyor systems, pumps, fans, and compressors where PWM switching noise must be attenuated.
- HVAC & Building Automation – Used in motor drive enclosures to suppress high-frequency harmonics that interfere with BMS sensors and control wiring.
- Water Treatment & Pumping Stations – Protects downstream instrumentation from drive-induced EMI in wet and harsh environments.
- Packaging & Material Handling – Ensures clean analog/digital feedback signals in high-speed servo and drive applications.
- Power Generation & Utilities – Deployed in drive control boards where grid-side noise filtering is required for stable operation.

Why Engineers Specify This Model
- OEM Compatibility – Designed specifically for HITACHI drive platforms; ensures plug-and-play replacement without parameter reconfiguration.
- Signal Integrity – Eliminates noise-induced faults on analog speed reference and feedback signals (0–10 V / 4–20 mA).
- Reduced Downtime – Direct board-level replacement avoids full drive changeout, cutting maintenance time significantly.
- EMC Compliance Support – Assists system integrators in meeting CE/EMC directives by reducing conducted and radiated emissions from the drive.
- Proven Field Reliability – Widely specified by OEM panel builders and MRO teams across Asia-Pacific and European industrial markets.
Complete System Bill of Materials
When specifying the LPF200A for a drive maintenance or new-build project, consider the following complementary components:
- HITACHI L200 / SJ200 / WJ200 Series AC Drive (main unit)
- HITACHI OPE-SR / OPE-SRmini Remote Operator Panel
- HITACHI EzSQ Programming Software (for parameter backup)
- Input Line Reactor (ACL series) – upstream harmonic mitigation
- Output dV/dt Filter – motor cable protection for long-run installations
- Shielded control cable (Belden 9501 or equivalent) – signal wiring best practice
- DIN rail terminal blocks and ferrite cores – panel-level EMI management
Compliance & Industry Standards
- CE Marking – Supports drive system compliance with EU EMC Directive 2014/30/EU
- RoHS – Manufactured in accordance with RoHS 2 (2011/65/EU) restrictions on hazardous substances
- IEC 61800-3 – Compatible with Category C2/C3 EMC requirements for adjustable speed electrical power drive systems
- UL Recognition – HITACHI drive platforms carry UL/cUL listing; filter board is OEM-matched to listed assemblies

Application-Specific FAQ
Q: Is the LPF200A compatible with the HITACHI WJ200 series?
A: The LPF200A is primarily designed for the L200/SJ200 platform. Compatibility with WJ200 should be confirmed against the WJ200 service manual or by contacting our technical team before ordering.
Q: Can this filter board be retrofitted into a third-party drive?
A: No. The LPF200A is an OEM-specific PCB designed for HITACHI drive internal architecture. It is not a universal filter and should only be installed in compatible HITACHI drive models.
Q: What symptoms indicate the LPF200A needs replacement?
A: Common indicators include erratic speed reference behavior, analog input noise faults (e.g., E07/E09 on HITACHI drives), unstable PID feedback, or visible PCB damage (burnt traces, swollen capacitors).
Q: Do you provide installation support?
A: Yes. Our technical team can provide wiring diagrams and installation guidance. Contact support@konmask.com with your drive model and application details.
Q: Is a warranty provided?
A: All new OEM parts carry a 12-month warranty against manufacturing defects from the date of shipment.
