60A DC / Continuous Pulse Current Source

The SpikeSafe™ 60A DC / Continuous Pulse Current Source is part of the SpikeSafe DC / Continuous Pulse Current Source family. This current source provides reliable and accurate DC or continuous pulse current drive at compliance voltages up to 50V. 60A DC / Continuous Pulse Current Sources feature precision pulsing with 10us minimum pulse widths and microsecond rise times. This current source is optimized for Laser Diode, VCSEL, and LED reliability, burn-in, IESNA LM-80, and other test applications requiring DC or pulsed current. The 60A source channel delivers up to 3000W 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 nanosecond rise and fall times. Pulses from multiple instruments may be synchronized. Multiple output conductor pairs keep maximum current per conductor below 7.5A, allowing the current output to be routed through standard interconnect devices. 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. This current source has a maximum compliance voltage of 50V. Its maximum current is 60A, with an output current accuracy of 0.2%+8mA, and a pulse width range of 10µs-15000s.

60A Source Pulse Shapes

Precision pulsing is key to best practices measurements. The 60A 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). Pulse width accuracy is 2.3us with pulse rise and fall times of 3us to 7us. Ramp time is adjustable from 1000V/s, 400A/s to 10V/s, 400mA/s.

Performance Curves

This model includes is available for use with an internal power supply (300W or 600W). For total output power (3kW), an auxiliary power supply is required. Please consult Vektrex for auxiliary power supply recommendations.
