UTL - Chargers

upsINVERTER.com is pioneer in both phase control chargers as well as CVCC chargers. Whatever is the rating & panel requirement can be met within time & within budget. Battery feels very relaxed if charged through UTL chargers.

We normally manufacture industrial or custom based chargers as per customers’ requirements and specifications

Phase Control Charger Details
Battery is fed a constant boost charging current until the voltage of each Battery reaches 14.2 V and then float current (very close to zero) maintains it above 12.9 V. Thus float current (flowing for the longest period in all this process) is reduced to nearly zero, ultimately resulting in much enhanced battery life, while keeping it fully charged simultaneously. In this boost constant current charging session, the current is almost constant on any input voltage 150 V to 290 V.

BATTERY BACKUP
It is a major problem while using the EPABX one faces, when power fails. The time delay in operating the generator comes out to be disastrous break in line and alternatively use of Inverters or UPS results in mind boggling distortion. The batteries generally connected with EPABX for the odd hours normally do not work proper, for these

Are not fully charged due to system's insufficiently slow charging
1. Could be deep discharged because of no series protection
2. Can not be charged if once deep discharged
3. Generally overcharged in case of higher main voltages and not charged in case of lower main supply
4. Can cause loading of the EPABX DC Supply forcing the EPABX to malfunction
5. Are equipped with unregulated charging, causing poor battery life ultimately

UTL's BATTERY backup is an all rounding solution to the problem occurring with your EPABX such ways, presenting the customer with the go-ahead of all the preconceived communication without any break or distortion.

Though it can be your specifications and details according to which we manufacture power Backup yet most of the EPABX 's in market are designed on 24 V DC supply, that is why we have 24 V Power Backup all time ready and hence the details for sample.
