Avtron LC20 Liquid-Cooled Load Bank (500kW)

The Avtron LC20 Liquid-Cooled Resistive Load Bank is designed for data center commissioning and testing while integrating seamlessly with existing cooling infrastructure.

FEATURES

• Load Capacity Option #1: Up to 500 kW at 480 VAC 3PH 60Hz.
• Load Capacity Option #2: Up to 500 kW at 415 VAC 3PH 50/60Hz.
• Load Step Resolution: 5kW at 480 or 415V.
• Controller: The Avtron RxMS controller integrates both liquid cooled and air-cooled load banks within the same network, managing up to 200 load banks from a single Windows-based interface. It supports TCP/IP Modbus communication, utilizing an Ethernet-based wiring infrastructure for seamless connectivity. The control panel features power on/off functions, master load on/off management, and alarm indicators for low flow, over-temperature, and over-pressure conditions, and control power internal/external switch, as well as a notification for remote mode and two Ethernet connections.
• Instrumentation: An integrated Shark power meter displays AC 3-phase voltage and current, power (kW), frequency, and power factor.
• Control Power: Power is either derived externally from the control power receptacle located on the front of the unit or internally from a control power transformer. If external power is used, 120V, single Phase, 60 Hz, 5 amp power source is required for the control circuits.
• Cooling System: The liquid cooled load bank has corrosion resistant stainless steel tanks and piping. The unit has 2 tanks, inlet & outlet piping with 4″ NPT thread connections, and resistors/elements on inside of the tanks. Avtron liquid cooled load banks have the capability to monitor flow (40 gpm minimum; 300 gpm max), pressure (rated 70 psi working pressure; 105 psi testing pressure), and temperature (170°F [77°C] Max. Water Outlet; 90°F [32°C] Max. Temperature Change). Ability to fully drain system to avoid cross contamination between jobs.
• Load Elements: The heating elements are immersion type, constructed from Incoloy 800, and feature a stainless steel screw plug
  mounting for secure installation. The elements are continuously rated at the specific voltage. Tests at lower voltages, with a corresponding reduction in overall rating, may be carried out.
• Safety Features: Thermocouples monitor temperature, triggering a resistor elements shutdown if high readings are detected by the iLB
  software. Rugged pressure sensors measure pressure, shutting down the resistor elements if high-pressure levels are identified. A magmeter tracks flow rate and the resistor elements shut down if flow drops below 40 GPM. The load bank contains fuses for short circuit protection. The control circuit is protected with a 10 amp fuse while the individual load steps have branch circuit fuse protection.
• Load Connections: Quick-connect male cam-type connectors. Three cam-connections per phase plus one ground.
• Construction/Enclosure: Heavy gauge aluminized steel per ASTM A463. Designed for continuous indoor operation. Sturdy welded frame and heavy-duty 6″ nylon castors are provided for easy mobility, durability, and long life.
