AC Load Bank (Resistive/Reactive)
K-1000 Resistive/Reactive
Kongter Test & Measurement Co., Limited
Resistive/reactive load banks are great choices for testing turbines, switchgear, rotary UPS, generators and UPS systems. They can also be used for integrated system testing of utility substation protection systems, particularly for more complex relays like distance, directional overcurrent, power directional and others. A resistive/reactive inductive and/or capacitive load is often required to test solar inverters to ensure solar panels can be stopped from producing electricity in the event of a power outage.

Current Mirrors
Analog Devices current mirrors are precision, high dynamic range, wide variable supply parts used for optical power monitoring, voltage biasing with current monitoring, and voltage-to-current conversion. Our current mirrors can monitor current down to as little as 3 nA and as much as 3 mA, with a linearity of 1% or better. The current dynamic range is 120 dB or 6 decades of current range, while the overcurrent protection feature in our devices forces the input pin to ground to avoid part damage. Over temperature (–40°C to +85°C) and process, the dynamic range only suffers 10 dB at the lower end of the range.

AC / DC - Power Supplies
The spectrum of DC power supplies ranges from simple power adapters with only one output voltage to complex controllable power sources. Power adapters, often also called plug-in mains adapters, are mainly used for small electrical appliances (such as telephones, strings of light, notebooks, etc.) in private households. They are included in the scope of delivery of the product and only serve to supply power with a defined output voltage of 6 V or 12 V, for example. The output power is usually limited to < 200 W due to the simple design.

Test Bench for AC Compressors
MS111
The test bench is intended to test AC compressors of wide range of vehicles on R134a refrigerant. The equipment detects failures of a vehicle unit before its mounting in a car, whether it is a remanufactured, repaired unit or a used one. In the process of testing, data is shown on LCD display. It gives an opportunity to follow testing results realtime, save and/or print them due to software special features. Unit fixation mechanism is very flexible: a compressor can be easily fixed, no matter what kind of fittings it has. Units with electromagnetic clutch or electromagnetic valve can be tested both separately and simultaneously. Peculiar features of electric commutation are considered, connection polarity is identified automatically, indicator on the control panel indicates on presence of a diode in a circuit.

Lightning Current Generator
Shanghai Guantu Technology Co., Ltd.
The lightning wave impulse current generator is an impulse current generator that generates a simulated lightning current waveform . Its working process is as follows: first, the transformer charges the capacitor bank through the silicon pile, when the charging voltage reaches a predetermined value, the spark gap is triggered, and the capacitor is discharged through the total inductance and total resistance of the circuit. When the resistance is greater than or equal to the critical damping value, a unidirectional impulse current wave is generated in the circuit. When the resistance is less than the critical damping value, an oscillating impulse current wave is generated. The magnitude of the impact current amplitude is related to the circuit parameters. When the capacitance value and charging voltage are the same, the smaller the inductance value, the greater the current amplitude. In order to obtain as much current as possible, a pulse capacitor with a small inductance value is usually selected, and the total length of the connecting line should be as short as possible when arranging the main capacitor, so that the total loop inductance value can be reduced as much as possible.
