Total Disconnect System
The Total Disconnect System’ (TDS) is an optional fail-safe system that protects the Users site from interruption of power if the PropSava or LiteSava require maintenance. The PropSava and LiteSava ‘cutting-edge safety systems coupled with the TDS seamless power control adds greater security for continuity of power supply and protection of the site.
This revolutionary system designed and developed by VP ensures that if the PropSava needs servicing or maintenance the site will not suffer any loss of power at anytime. Power disconnection from the PropSava or LiteSava and reconnection is seamless.
VP recommends that the TDS be installed at any critical site - a site that cannot be disconnected from mains power for any reason such as hospitals, medical centres, schools, universities, data centres, hotels, airports, any public area or facility.
The TDS is fitted between the site MCCB and the site distribution board. The PropSava or LiteSava is then connected to the TDS. In the event that the PropSava or LiteSava needs to be completely isolated from the site power, without interruption of site electrical equipment or services the TDS key switch is simply turned OFF. The computer controlled system of the TDS automatically initiates a program to:
1. Switch-off regulation of the PropSava or LiteSava.
2. Connect power from the site MCCB directly to the distribution board in parallel.
3. Activation of a flashing LED and alarm that signifies that TDS is activated. An alarm mute button is provided.
4. Isolation of all power to the PropSava or LiteSava so that it can be maintained/repaired/removed safely.
5. Reconnection of the PropSava or LiteSava and start of regulation in parallel to the site power.
6. Disconnection of the direct site power.
7. An ‘Engineers’ switch to allow for the testing of the PropSava or LiteSava before it is connected to the site.
Another major benefit of the TDS is the shorter time the sites power is shut-down for first time installation of the PropSava or LiteSava. Connection and installation of the TDS is much faster than installing any main power equipment - about a 60% less. Once the TDS power cables are installed the site power can be instantly turned on. The PropSava or LiteSava can then be connected at a later time or date without any further power shutdown at the site.
Any maintenance of the PropSava or LiteSava can proceed safely without any power interruption to the site. The TDS is simple to activate at source or remotely by any non-technical staff and can be retrofitted to existing installations easily.
