Technical Information

NIMpact NIM Bin 7U

Ventilated 518mm deep 7U NIM bin with 12 slot. Aluminum construction with stabilized steel card guide structure. Power supply is fixed mounted rear side. For improved cooling a 2U high fan tray with 3 DC fans is mounted below the card cage.

The power-bus-system is equipped with 12 high-quality long-life NIM connectors on a power backplane. Connector pins made of massive brass, gold plated.
Simplified ½ slot wide control panel with on/off switch and status LED.

Current maximum ratings:

Voltage Line	Current / slot	Current / bin	Comment
+/-6V	13A	65A	sensed
+/-12V	13A	13A	sensed
+/-24V	13A	13A	sensed
GND	13
115V AC	-	0.5A	Secondary

All NIM bins have clean earth wired with 0,25mm²
