Power Command 3.3 Control Panel (Optional)
Specification Sheet
The Power Command® control system is a microprocessorbased genset monitoring, metering and control system designed to meet the demands of today’s engine driven gensets. The integration of all control functions into a single control system provides enhanced reliability and performance, compared to conventional genset control systems. These control systems have been designed and tested to meet the harsh environment in which gensets are typically applied.
Description
The PowerCommand genset control is suitable for use on a wide range of diesel and lean burn natural gas gensets in paralleling applications. The PowerCommand control is compatible with shunt or PMG excitation style. It is suitable for use with reconnectable or non-reconnectable generators, and it can be configured for any frequency, voltage and power connection from 120-600 VAC line-toline, 601-45,000 VAC with external PT. Power for this control system is derived from the genset starting batteries. The control functions over a voltage range from 8 VDC to 30 VDC.
Feature :
• 12 and 24 VDC battery operation.
• Digital voltage regulation - Three phase full wave FET type regulator compatible with either shunt or PMG systems. Sensing is three phase.
• Full authority engine communications (where applicable)
- Provides communication and control with the Engine Control Module (ECM).
• AmpSentry™ protection - for true alternator overcurrent protection.
• Genset monitoring - Monitors status of all critical engine and alternator functions.
• Digital genset metering (AC and DC).
• Genset battery monitoring system to sense and warn against a weak battery condition.
• Configurable for single or three phase AC metering.
• Engine starting - Includes relay drivers for starter, fuel shut off (FSO), glow plug/spark ignition power and switch B+ applications.
• Genset protection – Protects engine and alternator.
• Real time clock for fault and event time stamping.
• Exerciser clock and time of day start/stop initiate a test with or without load, or a Base Load or Peak Shave session.
• Digital Power Transfer Control (AMF) provides load transfer operation in open transition, closed transition, or soft (ramping) transfer modes.
• Extended Paralleling (Peak Shave/Base Load) regulates the genset real and reactive power output while paralleled to the utility. Power can be regulated at either the genset or utility bus monitoring point.
• Digital frequency synchronization and voltage matching.
• Isochronous Load Share
• Droop KW and KVAR Control
• Sync Check – The sync check function has adjustments for phase angle window, voltage window, frequency window and time delay.
• Utility/AC Bus metering and protection
• Advanced serviceability – using InPower™, a PC-based software service tool.
• Environmental protection – The control system is designed for reliable operation in harsh environments.
The main control board is a fully encapsulated module that is protected from the elements.
• ModBus interface for interconnecting to customer equipment.
• Configurable inputs and outputs – Four discrete inputs and four dry contact relay outputs.
• Warranty and service – Backed by a comprehensive warranty and worldwide distributor service network.
• Certifications – Suitable for use on gensets that are designed, manufactured, tested and certified to relevant UL, NFPA, ISO, IEC, Mil Std. and CE standards.
Base control functions
