Circutor Computer 8d96 Manual Full ((hot))
This parameter defines the ratio weighting between the different capacitor steps. PROG Options: 1.1.1.1 - All capacitor steps are of equal kvar value.
The Computer 8d series is characterized by its ability to perform true RMS measurements and manage multiple capacitor steps.
The is part of the "Computer-8d" series of power factor regulators, which were historically produced in two sizes: the 96mm x 96mm Computer-8d-96 and the larger Computer-8d-144 for DIN 43 700 panel mounting. Manufactured by the Spanish company Circutor S.A., this regulator is designed for automatic power factor correction in electrical installations. It continuously monitors the grid's power factor (cos φ) and automatically connects or disconnects capacitor banks as needed.
Never disconnect the secondary of the current transformer without short-circuiting it first. Leaving a CT secondary open can cause a massive overvoltage, destroying the device and creating a lethal shock hazard. 🔌 Installation Guide

Capacitor banks generate significant heat. Ensure the enclosure fan is clean and operational to prevent the Computer 8d96 internal circuitry from overheating.
The instruction manual for the Circutor Computer 8d-96 (and the similar 8d-144 model) provides details on the installation, operation, and programming of this power factor regulator. Key Technical Specifications Measurement Type: True RMS measurements. Features an LED display for viewing parameters. Configuration: This parameter defines the ratio weighting between the
: Features a digital LED display for real-time monitoring of electrical parameters like , voltage, and current.
The Circutor Computer 8d96 features a user-programmable setup menu accessed via the front-panel keyboard. You will need to configure several key parameters: 1. Primary Current Transformer (C/k) Ratio
Units must be properly grounded before power is applied.
This critical parameter must be set based on the power of the first capacitor step and the CT ratio to ensure the regulator detects when a step should be added or removed. Target : The desired power factor to be maintained (typically or a value between Ind and Ind). Program Selection: Defines the ratio between steps (e.g., , , or ) depending on the capacitor bank configuration. The is part of the "Computer-8d" series of
: Re-calculate the C/K value using the formula provided in Section 3 and increase the value slightly. Over-Compensation / Capacitive Alarm Active
Monthly inspect the front panel to verify if any specific steps are constantly cycling, which indicates a setting imbalance or a failed capacitor unit.
