BID SPECIFICATIONS FOR 

3000VA, 5000VA and 6000 VA Smart-UPS RT 230VAC 

Uninterruptible Power Supply 

 
 

PART 1 - GENERAL 

1.1 

SUMMARY 

A. 

This specification describes the operation and functionality of a continuous duty, single-
phase, solid-state, static Uninterruptible Power System (UPS) hereafter referred to as 
the UPS. 

B. 

The UPS utilizes double conversion online topology designed to protect electronic 
equipment by supplying reliable, network-grade power featuring extremely tight 
voltage and frequency regulation. The UPS also features internal bypass and input 
power factor correction. 

C. 

The primary sections of the UPS are: input disconnect and filter stage, input PFC power 
stage, energy storage stage (DC bus capacitor bank), output power stage (inverter), 
bypass and a battery charger. The control of power module and fault detection logic is 
microcontroller based. Input disconnect and filter stage contains input backfeed relay 
(in models with a input wire plug), input filter, transient suppression, battery select 
transfer relays. Input PFC power stage contains non-isolated power factor correcting 
AC/DC converters.  This converter is capable of full power operation in very wide input 
voltage range or from a nominal DC battery voltage. The energy storage stage is a split 
DC bus capacitor handling seamless transitions from battery to line and vice versa as 
well as the low and high frequency power stages ripple.  The inverter stage operates 
directly from the DC bus and produces an AC output voltage of 
200/208/220/230/240VAC output. The output of UPS is either connected through a 
bypass relay to the inverter or to the input filtered line. UPS contains a battery charger, 
which operates from the DC bus.  

D. 

The UPS batteries are modular, hot-swappable, user-replaceable. 

E. 

In addition, this specification describes the performance, functionality, and design of 
the UPS Service Bypass Panel, hereafter referred to as the SBP, the external Battery 
Systems, and connectivity solutions. 

F. 

The UPS and associated equipment shall operate in conjunction with a primary power 
supply and an output distribution system to provide quality uninterrupted power for 
mission critical, electronic equipment load. 

G. 

All programming and miscellaneous components for a fully operational system as 
described in this specification shall be available as part of the UPS.
