10A Precision Pulsed Source – Performance Series

The SpikeSafe™ 10A Performance Series Current Source is part of the SpikeSafe Performance Series Precision Pulsed Current Source Family. It incorporates continuous power conversion, which means no duty cycle or pulse width limitations. Output pulses have nanosecond rise and fall times – key to precise LED, VCSEL, and LIDAR photometric and electrical measurements. A precision hardware-controlled timing system supports pulse widths from 1µs to 15000s. This current source supplies precision DC, continuous pulse, and single pulse current with excellent pulse fidelity. Programmable load tuning alters the SpikeSafe to compensate for load conditions, cable impedance and length. Hardware triggering ensures measurement repeatability. Multiple output conductor pairs keep maximum current/conductor below 5A, allowing the current output to be routed through standard switching and interconnect devices.

An optional bias current module supports junction temperature (Tj), thermal resistance (RΘ), and dynamic thermal impedance measurements.

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 the drive current when device anomalies are detected.

The notable specifications for this current source are as follows: the low range output current accuracy is 0.04%+350µA. The high range output current accuracy is 0.08%+2mA. The pulse width range is 1µs-15000s and the pulse width accuracy is 1µs. The pulse rise/fall time is 200ns-3µs and the typical pulse width jitter is 30ns.

10A Source Pulse Shapes

Precision pulsing is key to best practices measurements. The 10A 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 nanosecond pulse rise and fall times. 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 4 independent  source channels (4 x 1.6kW = 6.4kW), an auxiliary power supply is required. Please consult Vektrex for auxiliary power supply recommendations.
