Power conditioner and backup for security scanning equipment

A power conditioning system for providing clean and uninterrupted power to loads, comprising:

• a cabinet,
• an input circuit for receiving AC power,
• an AC to DC converter receiving AC power from said input circuit, a high frequency DC to AC inverter,
• an output circuit including a passive filter receiving power produced by said high frequency DC to AC inverter,
• two banks of batteries, said system configured to receive DC power from either of said banks to produce AC power by said high frequency DC to AC inverter such that the connection of both battery banks is not necessary to operate said high frequency DC to AC inverter, said system further configured to allow replacement of batteries in one of said banks while supplying power to said high frequency inverter from another of said battery banks, further wherein said banks are organized in a front and rear vertical rack, each rack providing access to each individual battery without the removal of other batteries, wherein the front rack may be rotated to provide access to the rear rack;
• a battery charging circuit receiving internal DC power, said battery charging circuit connected to provide charging for said batteries, and
• a main breaker or switch, and wherein the system prevents current from flowing from said batteries onto DC busses when said main breaker or switch is thrown.

A power conditioning system for providing clean and uninterrupted power to loads, comprising:

• a cabinet;
• an input circuit for receiving AC power;
• an AC to DC converter receiving AC power from said input circuit;
• a high frequency DC to AC inverter utilizing pulse width modulation at about 50 kHz to produce AC power output;
• an output circuit including a passive filter receiving power produced by said high frequency DC to AC inverter;
• two banks of batteries, said system configured to receive DC power from either of said banks to produce AC power by said high frequency DC to AC inverter such that the connection of both battery banks is not necessary to operate said high frequency DC to AC inverter, said system further configured to allow replacement of batteries in one of said banks while supplying power to said high frequency inverter from the other battery bank, further wherein said banks are organized in a front and rear vertical rack, each rack providing access to each individual battery without the removal of other batteries, wherein the front rack may be pivoted to provide access to the rear rack;
• a battery charging circuit receiving internal DC power, said battery charging circuit connected to provide charging for said batteries;
• a CPU-controlled battery charging circuit that charges at either a normal rate or a boost rate if batteries are discharged to a minimum voltage level or below;
• and
• a main breaker or switch, and wherein the system prevents current from flowing from said batteries onto DC busses when said main breaker or switch is thrown.
