TTi Laboratory Power Supply Products

 New safety binding-post terminals for laboratory power supplies from TTi

Now being fitted to CPX, EL, EL-P, EX, EX-R, EX-P, QL and QL-P series models

Why was a new design needed ?

The terminals used on the majority of laboratory power supplies are in the form of binding posts (Fig. 1) that can accept 4mm open plugs into the front, and bare wires or spade terminals into the body.

However, concern over personal safety has caused an increasing number of organisations to prohibit the use of bare ended connections within a laboratory environment.  Instead, they stipulate that all connections must be made using shrouded 4mm plugs which are incompatible with normal 4mm binding post terminals.

Until now, the only solution for these organisations has been to purchase power supplies fitted with 4mm safety sockets similar to those used on digital multimeters (Fig. 2). These power supplies are restricted to use with 4mm plugs only, and have no facility for accepting bare wires or spade terminals.

The TTi Solution

TTi wanted to offer a product that was fully compatible with the requirements of organisations who require that all connections are made with shrouded plugs, whilst retaining the flexibility accept all forms of bare ended connections.

The new terminal design (Fig. 3) does exactly that, and is exclusive to TTi power supplies.

     The new terminals are compatible with
     any type of connection from bare wires
     through to shrouded 4mm safety plugs

The limited opening distance of the terminal ensures that the clearances are sufficient to make the exposed metal parts "touch proof" when voltages in excess of "extra low voltage" are being used.

Please Note:

The product illustrations within the description pages and PDF brochures on this website may not yet reflect the use of the new safety terminals.
