Intelligent Power Module (IPM) Transistors with Excellent Performance Characteristics
Mitsubishi Electric is the leading manufacturer of Intelligent Power Modules (IPMs), and now utilizes Intelligent Power Module transistors in the converters and inverters of its 2033A Series UPS systems. These advanced, highperformance transistors provide a variety of intelligent features.
Drive Circuitry
Overcurrent Protection
Over Temperature Protection
Control Voltage Drop Protection
Short-Circuit Protection
Low Input Current Harmonics (THD)
3% maximum (100% load)
4% maximum (75% load)
6% maximum (50% load) (No additional filtering required)
Input Power Factor
1:1 ratio
Low Heat Loss / High Efficiency
Use of Intelligent Power Module transistors enables efficient high-speed switching (6kHz), thus reducing heat dissipation in the UPS. (Higher efficiency means lower cost per kilowatt to the customer.)
Extended Battery Life
Current source from batteries for step loads is no longer required with the installation of Intelligent Power Module transistors in both the converter and the inverter. Previous UPS systems required assistance from batteries when the converter was unable to supply the required current. This cycling of batteries caused shorter life.
Mitsubishi Electric Intelligent Power Modules incorporate the latest technologies and provide step load applications (0-100%) without the use of batteries, thus ensuring maximum battery service life (i.e., lower lifetime cost of UPS system).
Internal Maintenance Bypass
All 2033A Series UPS systems are equipped with an internal wrap around maintenance bypass system for greater maintenance flexibility.
UL 1778 approved
Superior Control
All 2033A Series UPS systems
use pulse width modulation
(PWM) for superior control and
performance. A digital signal
processor (DSP) ensures
precise control of all input / output
parameters.
