First, the split is Load cabinet Applications:

The company mainly produces 1KW-2000KW For DC, 50HZ AC generator power, ship, radio and television, telecommunications and other departments and manufacturers of high-power line ups , Inverter, switching power supply and diesel generator sets of performance testing, aging and other occasions. Unified sub-type power input, energy consumption mode of operation, forced air-cooled heat, greatly guarantee the reliability of constant power discharge; with the new Power components of independent intellectual property rights, with high power density, no red hot phenomenon, overheating automatic protection function, the fan does not turn the case, it will not occur overheating, burning the situation, long life; Design, simple operation, easy maintenance; according to customer requirements test voltage, current and other parameters for high-power AC power supply equipment to provide a scientific means of detection. And according to customer requirements to design a variety of different requirements of the load box.

Second, the load cabinet Category:

1, In order to enhance the utilization of equipment, the company designed the load box can be made into sub-file adjustable and stepless adjustable, available switch sub-file and contactor sub-file, in order to meet the different power and different current load test needs;

2, Through the contactor control, can be different voltage, different power, different current test set in a load box, a common set of resistive elements;

3, According to different uses of the load box can be designed to standard, mobile type, impact resistance type;

(1) Standard type: suitable for high precision, the workplace is relatively fixed, indoor use of the load box. Resistance temperature coefficient is small, the error of constant copper or manganese copper manufacturing, but larger.

(2) Mobile type: suitable for outdoor use, often moving, small size, light weight, simple structure, good shock resistance. Resistance elements using high-temperature electric alloy material, but strong wind cooling.

(3) Resistance to shock: suitable for overload capacity requirements, often overload operation. Resistance of stainless steel components, but the high temperature coefficient.

4, RLC Load box

(1) Resistive load, high resistance can be achieved without the standard sense, inductance ≤4Lt; / RTI & gt;H.

(2) Inductive load using solid-type sub-reactance, loss of small, high efficiency, input accuracy, no adjustment; special requirements can be made continuously adjustable inductance.

5, Load box Can be equipped with temperature protection or wind pressure protection, only in the temperature or fan start to allow the case of the load box to work properly, there is overheating or fan abnormal temperature, the protective device will immediately issue instruction removal load to prevent damage due to insufficient cooling resistance components .

6, The load heat dissipation using the level of access to the wind and the next two ways, according to the different needs of the set.

Third, the main function of the load cabinet:

(1) Users can adjust the discharge power according to performance parameters, testing requirements, set.

(2) Digital table shows the voltage, current and other parameter values.

(3) The machine adopts the new power consumption components, with overheating automatic blocking protection.

(4) AC load box with resistive, inductive, capacitive load.

Optional function

Automatic AC load cabinet: digital table shows: power, voltage, current detection value.

Intelligent AC Load Cabinetled ) : 0.5Level multi-function digital instrumentation, detection and display: AC voltage, current, active power, power factor, frequency. RS485Computer interface, and PC Machine communication.

Intelligent AC Load CabinetLCD ): Dedicated LCD display: AC voltage, current, active power, power factor, voltage frequency; and 1-40Sub - harmonic analysis RS485Computer interface, and PC Machine communication.

four, Load cabinet Mian Technical Parameters

(1) Power from 1KW-1000KW , Sub-set, plus or minus gear to the required power value or current value.

Normally set to: Example 10KW (100W, 200W, 200W, 500W, 5KW)

(2) Forced by the use of forced air, left into the right or right into the left wind, or down into the wind.

(3) Box size is generally 10kw-20kw (580 * 450 * 1100) mm (With universal casters mobile) , 30kw-50KW (1000 * 450 * 1100) mm (With universal casters mobile)

(4) Load protection function: over temperature alarm Over temperature protection Overcurrent protection Short circuit protection

Specifications: Voltage AC220V-400V , Power 1kW-1000KW ; Can be selected according to demand.
