The NeuroLog™ module frame and power supply are housed in a fully finished, enclosed case. The case has handles and integral rack mounting hardware so that it can be shifted directly between rack and bench top. The case contains 13 module bays plus power supply panel.
The NeuroLog™ case has an integral module retention system, consisting of a simple, slide action lever on the power supply panel. Therefore, fittings such as retained screws, D-locks, etc., on individual module front panels are unnecessary. This simple design enables easy, rapid, changes in module arrangements, and ultimately reduces the cost of the modules.
The NeuroLog™ power supply produces three voltages (+15 V, +5 V, and -15 V), stabilized against line and load variations. The voltage outputs are rated at 650 mA, 3.0A, and 650 mA, respectively. All three supplies have internal ‘fold-over’ current limiting; the 15V supplies, in addition, are protected with series fuses. Each supply has less than 15 mV line ripple at maximum load. The power supply transformer employs a sectionalized winding former for additional safety and complies with the requirements of IEC601 part 1 and BS5724. The power supply provides sufficient power for almost any mix of NeuroLog™ modules.
A unique feature of the NeuroLog™ power supply is a built-in logic circuit which indicates (by extinguishing the power supply indicator on the front panel) excessive loading of one or more of the three supply outputs. While it is expected that a power supply failure will never occur using NeuroLog™ modules, the fault indication is invaluable when testing custom circuits built in the NL50 Blank Module.
