NC48 Tech Notes

HV250 vs NC48 features


Product: HV250, NC48
Version: All
Date Added: 2006-10-11


TDT often recommends the NC48 due to its longer battery life. Investigators who use silicon probes, such as the NeuroNexus probes, find that the impedances of the probes drop in the range of 100 kOhms when the probes are activated for stimulation. As a result, a compliance voltage of ±24 Volts work fine in most cases.

Compliance Voltage ± 135 Volts ± 24 Volts
Max impedance for 100 microAmp stim 1 MOhm 200 kOhm
Usable in 1 milliAmp mode No Yes

If you have an HV250 battery pack and think you might benefit from switching to the NC48, contact TDT for more information.
