No. The outputs of a DD40 cannot be paralleled. If you need higher current drive, please contact us.
Can I Connect Two Ice Bloc Diode Drivers In Parallel To Achieve Higher Drive Current For A Single Diode?
No. The output current of each unit is carefully monitored and stabilised, so combining the outputs in parallel may lead to instability. If you need to drive a high-power diode, consider our DD-40 Ice Bloc offering up to 40A per channel, or contact us for further enquiries.
Yes, under a supervisor login the maximum drive current, maximum compliance voltage and current ramp rate can be set, per channel. In addition, should a channel be enabled with no diode connected it will be immediately shut down. However, as for every high current system, extreme care must betaken to ensure that the electrical connections […]
Yes, both laser diodes and light-emitting diodes can be controlled by an Ice Bloc diode driver. The maximum output compliance of the DD40 is5V which is enough to drive most single LEDs but may be too low for some high power white / blue LEDs.
The external modulation bandwidth of a DD40 channel is affected by the output current being drawn from the channel and the modulation depth. It is primarily a CW diode driver with modulation inputs. For small signal modulation (keeping the diode above threshold) the modulation bandwidth is useful up to about 20kHz. For deep modulation (going […]
The DD-40 has a maximum power output for all four channels and a maximum output per channel. When you configure each channel with the maximum current and compliance voltage limit for the connected diodes, the total power is calculated and may limit what is available on the remaining channels. If the compliance voltage limit is […]
