We make instruments better, not cheaper. This is reflected in our Standard TB3 NIM Bin which uses extruded aluminum construction, paralel wired power distribution and floating bin sockets. We now offer a Bin with an additional feature – voltage monitoring LEDs. The new TB4 gives added assurance by illuminating a gren LED on all active supply lines within regulated limits. The TB4 is the perfect mat efor the new TC 911 TURBO or our Standard TC 911 supply and it is even compatible with supplies from those other guys.
