Page 4: Overview
Overview: The LB-TFPS-180-540-90UI T-Former indoor power supply is a pure sine wave adjustable power supply (180 to 540VA), with the highest- efficiency, and most reliable technology. With almost double the lifetime of comparable Ferro-Resonant products, it delivers at least 5% energy savings compared with standard systems. -
Page 5: Technology
Technology • The LB-TFPS-180-540-90UI utilizes a unique US Patent AC/AC variable ratio transformation which provides ultimate voltage regulation and pure sine voltage output at all loads. Input & output Voltage are completely isolated. Line conditioning enables the changing of “gears” at O time "zero crossing". - Page 6 Basic Block Diagram Figure 2: Block Diagram T-Former Power Supply...

Page 12: Installation And Operation
Installation and Operation: • The LB-TFPS-180-540-90UI power supply is factory assembled at 6 Amp maximum on the output port. The output port has a T8.0A fuse. • System reliability depends on protecting the power supply from overcurrent events. Through proper fuse selection, you can minimize risks and failures. - Page 13 • Adjust dip switches for desired output current. (Refer to Figure 10). • Adjusting the power manually allows the operator to pay flat rate for the real energy consumed instead of paying for the Power Supply rated power. DIP Switch Position Current Limit -90V Figure 11: DIP Switch Adjustment...
