Ecostar Eco5-TP4V300-24J – SCR | Eco5-TP | Three Phase Thyristor Power Regulator (300Amp)

Product features

• Allows independent adjustment of Max and BIAS settings.
• Features a down-opened panel for easy fuse replacement.
• Front panel installation of VR for Max and SFS adjustment for user convenience.
• Multi-LED display panel for clear indication of operating conditions.
• Independent control of auxiliary powers (AC1, AC2) for all models.
• Includes built-in buffering output adjustment (SFS VR) with a range of 1 to 22 seconds (only applicable to phase control products).
• Safety and aesthetic considerations with top and bottom shielding covers for easy wiring installation.
• Features immediate system output switch-off in the event of sudden 0.5 Hz power loss, with subsequent buffering upon power restoration to prevent voltage surges and fuse damage.
• Designed for main power specifications ranging from 200 to 480VAC.
• Automatically detects power frequency within the range of 50 to 60 Hz without the need for manual selection or switching.
• Provides automatic detection and display of power out-of-phase, SCR overheating, and fuse burn-down, with corresponding alarm dry contact output.
• Automatically stops system output in cases of SCR overheating or fuse burn-down, with subsequent buffering upon malfunction resolution and power restoration.
• Offers compatibility with various control signals including 420mA, 15VDC, 210VDC,
• Includes separate triggering circuit and main board design to prevent main board damage during main circuit malfunctions.
• Utilizes European detachable control signal connectors for easy replacement without requiring rewiring.

Outline description

Installation and ambient conditions

• During operation, the power regulator generates heat. It is recommended to install the system vertically with space on two sides to prevent continuous temperature rise inside the regulator.
• Ventilation holes in the control box should be installed following the principle of upward air movement or with additional cooling fans.
• Avoid installation in areas with high temperatures or poor ventilation to maintain operating capacity below 70% of nominal capacity.
• Do not install in areas with heavy water evaporation, acidic, alkaline, or corrosive air.
• Ambient humidity should be below 90%RH to prevent condensation.
• Ambient temperature range for operation: -10°C to 45°C.
