Main circuit   power interface

IEC60309 three-phase   five-wire + N+E plug, 400V 63A, male socket.

Loading method

The panel is   equipped with a step switch (miniature circuit breaker) and manual loading

Control power   supply

Use the tested   power interface (L1-N) for power supply

Insulation level

AC1000V,   insulation resistance ≥10MΩ

Inlet water   temperature

2~100℃

Water circuit   interface

Equipped with 1   liquid inlet and 1 liquid return port , using clamp -type quick connector ,   pipe diameter: DN25, 50.5 chuck, pipeline with exhaust valve.

Pressure

The liquid   cooling vessel or resistor can withstand a working pressure of 1 MPa, and the   ultimate test pressure is 1.5 times the working pressure.

Airtightness

No leakage for 2   hours under 1Mpa pressure

Reference water   flow

0.5-5m³ / h

The equipment   pipeline is equipped with a built-in electric balancing valve, which can be   used to adjust the flow rate and flow resistance;

Cooling method

High-grade pure   water cooling

Insulation grade

F-Class

Protection level

IP23

Duty

Continuous work

Pipe material

All pipes are   made of 304 stainless steel .

Overtemperature   protection

The load is   equipped with inlet and outlet temperature monitoring, and the front display   has an over-temperature alarm indicator light.
  When the temperature is abnormal, an alarm will be issued and the device will   be unloaded (the upper limit of the inlet and outlet liquid temperature is   alarmed, and the value is adjustable (the default is 80℃).

Pressure   protection

The load can   monitor the inlet and outlet pressure of the liquid. When the pressure   exceeds the set value (the alarm value can be set), an alarm will be issued   and the load will be unloaded.

Overload   protection

Monitor the   power of the whole machine during load operation. When the power exceeds the   set value, an alarm will be triggered and the machine will be unloaded. The   alarm value is adjustable.

Short-circuit   protection

When short   circuit or overcurrent occurs, the step circuit breaker trips to protect   against damage to the equipment;

Grounding   protection

The input port   has a ground wire and is connected to the chassis. The chassis has a   grounding position for users to use for grounding.

Leakage   protection

The load   monitors the leakage status of the load water channel in real time. When   leakage occurs, the sound and light alarm prompts and the load is unloaded.

Protection   switch

Some protection   functions are equipped with switches, which can temporarily turn off the   corresponding protection function in case of false alarm or special needs.

Transportation

The front panel   has a handle and the bottom has casters for easy transportation.

Dimension

Volume: 6U,   approximately 430mm*267mm*750mm (width*height*depth), excluding the panel   handle and tail casters. The size can be adjusted and optimized appropriately   .

Colour

RAL2003

About 35kg

Human-machine   interface and display

The dummy load   is equipped with a local touch screen with inlet and outlet liquid   temperature display; inlet and outlet liquid pressure display; power,   current, voltage display, and flow display; temperature, pressure, flow and   other data display can be viewed locally , and curves and historical data can   be exported to a USB flash drive. The exported data can be used to generate   curves on the host computer and can be printed;
