LED Mode

The BK9170B/BK9180B series design incorporates special LED test modes for efficient and safe electrical tests of LED panels. Powering LEDs with conventional power supplies will potentially cause permanent damage to the UUT or limit its lifespan. This damage is caused by the excessive inrush current at power up and the non-linear characteristics of the LED’s I-V curve. These power supplies feature two distinct operating modes suitable for LED testing in a manufacturing or R&D environment and other special applications requiring a controlled rise time at power up without generating any inrush current.

Built-in simulations compliant to automotive test standards

In order to ensure electronic systems used in a vehicle are able to function in an automotive environment, automotive component manufacturers test electronic modules to industry standards.
The BK9115-AT provides automotive power test waveforms compliant to DIN 40839 and ISO 16750-2 standards that can simulate common test conditions for electrical and electronic devices installed in automobiles.

Even this series of power supplies have 4 different models, only one support these specific tests, the BK9115-AT.

BK9115 1200 W 80 V 60 A 1.860,00 €
BK9115-AT 1200 W 80 V 60 A 2.350,00 €
BK9116 1200 W 150 V 30 A 2.100,00 €
BK9117 3000 W 80 V 120 A 3.400,00 €

Still the other 3 models are very interesting as they can be easily connected in series or parallel to increase their voltage or current output.

Series Parallel
BK9115 3 units (240 V Max) 3 units (180 A Max)
BK9115-AT 3 units (240 V Max) 3 units (180 A Max)
BK9116 2 units (300 V Max) 4 units (120 A Max)
BK9117 3 units (240 V Max) 4 units (480 A Max)
 


Power line disturbance (PLD) simulator

The PLD simulator is an extended feature of list mode that provides the user with more control over the disturbance insertion into the waveform. This can be useful for evaluating a product’s immunity performance. For instance, a user could produce common waveform disturbances like surge, sag, spikes, and dropouts at  user-defined locations on the waveform.

 

PLD Simulation

 
 
This function is available in our range of AC Power Sources, where we have 5 different models. They have also present other important characteristic:
- Dimmer mode
- Voltage and frequency sweep mode Pre-compliance testing for voltage dips and frequency simulation according to IEC61000-4-11 / 4-14 / 4-2
- Low total harmonic distortion meets the IEC 61000-3-2 standard
- Built-in standard waveforms sine, square and clipped sine

Our 5 different models have a single-phase output but now it's possible to combine 3 different models of the BK9832B and BK9833B and have a 3-phase output up to 9000 VA.

BK9801 300 VA 300 V 3 A                   2.100,00 €
BK9803 750 VA 300 V 6 A                   3.070,00 €
