General purpose small-capacity UPS. 'MCL75/100', 'TCL75/100'

摘要

We have developed a single-phase output UPS "MCL" and a three-phase output UPS "TCL" as an intermediate capacity UPS for general purpose. The feature of these UPSs is to provide with the option circuits such as loads MCCB and the bypass transformers in spite of their small volume. Therefore, these UPSs can meet the demand of all customers. Moreover, the use of a 32 bits high-performance microcomputer has made the control circuit of UPS quite compact. As for converter circuits, the direct control was achieved completely. We can cope with the user who demands the complex sequence operation of UPS by using the microcomputer. The conversion efficiency was raised by using the latest IGBT for the power conversion semiconductor. These UPSs are made to be able to add a LAN conversion box which can be connected to the ETHERNET according to the construction of the information technology in the present age society. The high-performance and small valve-regulated lead-acid battery made by our company is used for the back-up storage battery of these UPSs, and so the battery discharge time and life are long to meet back-up demand. Moreover, to facilitate maintenance, all the exchange parts can be replaced from the UPS front. We expect these high-performance, small and low-price UPSs receive favorable comments from the customers in each field.
