Penerangan

Product Overview

The 8440-1935 (alternatively designated as the easYgen-3500-1-P1) is an advanced genset controller from Woodward's easYgen-3000 series. Housed in a durable sheet metal chassis designed for cabinet installation, this unit features integrated generator group breaker control. Weighing approximately 4.08 lbs (1,850 g) with front panel dimensions of 282W x 216H x 96D mm, it delivers high-precision power management with 16-bit resolution and an Accuracy Class of 0.5.

Core Technical Advantages

  • High-Precision Measurement: Engineered to Accuracy Class 0.5 with 16-bit resolution and a wide setting range from 1 to 32,000 A.
  • Integrated Breaker Control: Equipped with built-in generator group breaker control for seamless synchronization and switching.
  • Isolated Discrete Inputs: Features robust isolated discrete input channels to protect internal circuitry from field electrical noise.
  • Rugged Sheet Metal Build: Sturdy 1,850 g chassis built to withstand harsh industrial generator control environments.

Industrial Solutions

  • Standby & Prime Power Generators: Manages automatic start/stop, synchronization, and breaker control for diesel and gas generator sets.
  • Multi-Gen Paralleling Systems: Coordinates load sharing and power factor regulation across complex multi-generator installations.
  • Industrial Power Management: Provides reliable monitoring and protection in industrial switchgear and utility backup panels.

Wiring & Installation

Cabinet Mounting & Chassis Grounding

Install the controller inside a protective industrial cabinet using the 282W x 216H x 96D mm cutout profile. Do not connect wires directly to the protective earth terminal on the controller body; route any necessary ground connections exclusively through the designated bottom connector.

Current Transformer Safety Precaution

Always ensure that current transformers (CTs) are properly short-circuited before disconnecting wiring from the controller. Failing to short-circuit CTs during disconnection can result in hazardous high voltages, severe personal injury, or death.

Power Factor Configuration

Configure power factor parameters based on your system load type—capacitive, purely resistive (targeting unity 1.00 where voltage and current waveforms are in step), or inductive.

Engineering Advantages

  • Advanced Power Factor Management: Accurately calculates real-to-apparent power ratios across resistive, inductive, and capacitive circuit profiles.
  • Robust Isolation: Isolated discrete inputs safeguard internal processing components from heavy electrical transients.
  • Flexible Switchgear Integration: Built-in breaker control logic streamlines synchronization architecture in generator control panels.
