eCAP-9450 Multifunction Capacitor Controller

Based upon QEI’s field proven 6ACP6 platform, the eCAP-9450 provides three-phase, single-phase, 3-step, or 2-step capacitor bank control in a cost effective package.

When equipped with a suitable serial or TCP/IP based communication channel, the eCAP-9450 provides SCADA functionality via DNP3 or other current or legacy protocol from the 6ACP6 library in order to smoothly integrate with your larger distribution management system.

CONFIGWIZ® 2.0, our configuration software module, provides a user-friendly, drag-and-drop Windows® Interface for intuitive configuration and faster training in order to get you up and running quickly.

The eCAP-9450 accepts voltage and current inputs from either line post sensors or PTs and CTs. Capacitor switching may be based on either voltage or kVAR, with a local voltage override option included, which has precedence over kVAR control. Neutral current detection is also present.

The +12VDC, 2.0A power supply provides power for both the 6ACP6 board itself and a user supplied radio. Six control relay outputs (each rated at 10A/250VAC) are arranged as 3 trip/close pairs for independent or ganged control of three cap bank switches. Front panel switches are included for Phases A,B,C open/close and auto/ manual, local/remote and lock-out.

Front panel LED indicators and multi-line readout are included for easy assessment of operation.

Controls & Indications

  • Front Panel Switch Control: A,B,C Phase A,B,C open/close, auto/manual, local/remote and lock- out. Multi-line LED readout and LED indicators for assessment of operation.
  • CommFail: Revert to automatic local control if communications to the SCADA master station fails
  • Auto Control: Fully automatic control based on internal user-defined switching algorithms
  • Lockout: Failure detected – control operations blocked until reset either locally or from the SCADA master station

Safety

  • Burnout protection blocks all switch operations until line voltage reaches an acceptable level
  • Hunting protection to prevent excessive operations (user defined)
  • Operation retry rate as well as the total number of attempts can be user limited
  • Programmable time interval & retries for detecting neutral fault conditions

What Our Customers Have to Say

“Our relationship with QEI began in 1986 with the deployment of a PDP-11 based SCADA system and four RTUs. Over the decades, that system has been continuously upgraded and expanded to support the growing needs of our rail operations. QEI’s solutions have provided the real-time visibility, control, and reliability required for mission-critical traction power infrastructure. With hundreds of field RTUs installed and control houses to advanced master station software, QEI has remained a trusted technology partner in supporting safe and efficient operations across our network.”

The National Passenger Rail System across USA

“City of Concord has partnered with QEI since 1986, and throughout that time their solutions have continued to support our evolving operational needs. From early-generation RTUs to latest upgraded RTUs, capacitor controllers and multiple SCADA master station enhancements, QEI has been a dependable technology provider for our system. Our most recent investment in February 2025 to upgrade to QSCADA reflects the confidence we have built through decades of successful collaboration.”
