SECTION 2 – OVERVIEW
2.1 INTRODUCTION
The Protector 3 UPS system is designed for switch mode power supplies, computer loads, with no
derating, drawing sine-wave input current that is power factor corrected. The Protector 3 meets or
exceeds life safety codes of UL1778. These codes were established to allow the UPS to provide power
during a power failure.
When input power to the Protector 3 is lost during a power outage, the system will automatically draw
power from its internal battery supply without any interruption. The critical load will receive only clean
sine wave power. The optional output transformer allows multiple output voltages as well as input
voltages that are different than output voltages. The internal VRLA (valve regulated lead-acid),
maintenance-free batteries provide specified time of backup power.
Upon restoration of input power, the Protector 3 automatically resumes normal operation, and
immediately begins to recharge the batteries.
The Protector 3 has an internal bypass circuit, which maintains the power to the load in case of internal
UPS failure.
The Protector 3 provides comprehensive monitoring capabilities. In addition to the LCD display, it
provides five dry relay contacts for remote monitoring capabilities. The Protector 3 contains, as standard
features, an AS 400, RS 232 protocol interface, RS485 data transmission ports and many other
communication options.
The Protector 3 is an on-line three phase PWM inverter available in output rating of 10, 15, 20, 25, 30, 40,
50, and 62.5 kVA. The Protector 3 is listed for compliance to UL1778, UL924A and CSA107.1 Standards.
The Protector 3 is available with an input or output voltages of 480Y/277 or 208Y/120 VAC, three phase.
This information is provided on the nameplate located on the inside front door of the UPS. See Appendix
A for a complete listing of the Protector 3 specifications.
