The SpikeSafe 500mA DC/ Continuous Pulse Current Source is a member of the SpikeSafe Series DC / Continuous Pulse Current Source family. First of all, this model is available in single and multiple source channel modules. And this current source has a maximum of 8 independent source channels. Secondly, each of these source channels supply reliable and accurate DC and precision pulsed current. Moreover, the 500mA DC / Continuous Current Source is recommended for low current applications. Therefore, it is perfect for applications such as those requiring minimum currents of 10mA or less and a maximum current of 500mA. Especially noteworthy, is the fact that each source channel is independently controlled and delivers up to 200W of output power. In addition, this current source delivers that power with industry leading efficiency.
Most importantly, this current source delivers reliable and accurate DC and precision pulsed current. Further, it has a maximum compliance voltage of 400V. Above all, the 500mA DC/ Continuous Pulse Current Source enables high-capacity testing of low current devices. For example, assuming 3W devices, the SS400-DCP-400-05-2U8 will easily drive 125 devices per source channel; totaling 1,000 devices! The low range (to 40mA) current output accuracy is 0.05% + 10uA, and the high range current output accuracy is 0.05% + 75uA. Finally, the Setpoint resolution for this 500mA Current Source is 1uA.
500mA Source Pulse Shapes
Precision pulsing is key to best practices measurements. The 500mA 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 from 1000V/s, 5A/s to 10V/s, 50mA/s.
This model includes buck/boost and is available for use with an internal power supply (300W or 600W). For total output power across 8 source channels (8 x 200W = 1,600W), an auxiliary power supply is required. Please consult Vektrex for auxiliary power supply recommendations.
