5A DC / Continuous Pulse Current Source

The SpikeSafe™ 5A DC / Continuous Pulse Current Source is a member of the SpikeSafe DC / Continuous Pulse Current Source family. This programmable current source, introduced in 2005, is in use worldwide for high capacity LED, Laser Diode, or VCSEL reliability, burn-in, IESNA LM-80 and other testing applications that require constant current or pulsed current. Devices under test include LED, VCSEL, COB, LED modules and arrays and other current driven devices.  5A DC / Continuous Pulse Current Source are available with up to 8 individually controlled sources each supplying reliable and accurate DC or continuous pulse current drive at compliance voltages up to 200V.  With an industry-leading 96% power conversion efficiency, electricity costs and facility cooling needs are reduced 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 accurate constant and pulsed current to the ends of long cables. Sources channels may be synchronized or staggered for load balancing. A built-in data acquisition system samples 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. Output current accuracy is 0.04%+175µA. 

5A Source Pulse Shapes

Precision pulsing is key to best practices measurements. The 5A 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 available with upgrades for fast precision pulsing (1us pulse widths). Pulse width accuracy is 1us with pulse rise and fall times of 200ns to 3us. Ramp time is adjustable.

Performance Curves

This model s available for use with an internal power supply (300W or 600W). For total output power across 8 source channels (8 x 1,00W = 8,000W), an auxiliary power supply is required. Please consult Vektrex for auxiliary power supply recommendations.
