16A DC / Continuous Pulse Current Source

The SpikeSafe™ 16A DC / Continuous Pulse Current Source is a member of the SpikeSafe DC / Continuous Pulse Current Source family. This 16A multi channel programmable pulsed source provides 1 or 2 independent source channels of reliable and accurate DC or continuous pulse current drive at compliance voltages up to 200V.  The 16A DC / Continuous Pulse source is an ideal choice to power high voltage LED or laser devices or series circuits of high current devices.  Precision pulsing with 10us minimum pulse widths and nanosecond rise times keeps junction temperatures low. Each individually controlled source channel delivers up to 3200W of output power at an industry-leading 96% power conversion efficiency. High efficiency reduces electricity and facility cooling needs, lowering the total cost of ownership for systems. Continuous power conversion technology means no duty cycle or pulse width limitations.

Adjustable load tuning allows the SpikeSafe to compensate for load conditions, cable impedance, and length. The result is output pulses with microsecond rise and fall times. Pulses from multiple channels may be synchronized or staggered for load balancing. A built-in data acquisition system samples pulsed or DC voltage and current to support LM-80 monitoring requirements. Devices being tested are protected with a gentle turn-on during ramp-up, and with SpikeSafe load protection during operation. SpikeSafe load protection continuously monitors voltage and current patterns and instantly shuts down drive when device anomalies are detected preserving devices and improving yield. This multi channel source will support maximum currents to 16A, with an output current accuracy of 0.04%+700µA.

16A Source Pulse Shapes

Precision pulsing is key to best practices measurements. The 16A Precision Pulsed Current Source offers programmable pulse width flexibility. It is capable of long pulse widths (ms to seconds) and short pulse widths (100us pulse widths and faster). With the pulse source, minimum 10us pulse widths are possible without requiring major system upgrades.  Pulse width accuracy is 1us with pulse rise and fall times of 350ns to 6.5us. Ramp time is adjustable.


Performance Curves

This model is available for use with an internal power supply (300W or 600W). For total output power across 2 source channels (2 x 3.2kW = 6.4kW), an auxiliary power supply is required. Please consult Vektrex for auxiliary power supply recommendations.
