Uptech provides electronic backup power solutions in the form of UPS (uninterruptible power supply) systems. Our UPS backup power systems are suited to both small-medium-to-large enterprise and home environments.
Our single phase UPS series is offered from 1kVA to 20kVA and our 3-phase UPS series is offered from 10kVA to 600kVA, all available in single units. For capacities, up to 3MVA, the single units can be paralleled. The technical services we provide include UPS maintenance contracts, UPS repairs, and battery replacements.
Cost is an important consideration as the Rand is constantly under pressure from international currencies such as the Dollar and Euro. What is suitable in the US or Europe is not always viable in Africa. Each Installation we roll out is meticulously planned and implemented under the guidance of Michael Alhadeff who has 25 years of hands-on technical experience from being on-site, overseeing each and every installation, addressing and resolving problems, testing and maintaining a multitude of UPS systems which Uptech has installed over the past 20 years.
Uptech has extensive experience in electronic backup power solutions, with more than twenty years in the industry, originating in Pretoria. Uptech offers superior value in each of its power backup products and installations. We import, supply, install and service Uninterruptible Power Supplies (UPS''s) from 1kVA to 650kVA, including 3 phase UPS products.
Uptech is a leader in Small-Medium-Large Enterprise & Home Power Backup solutions in Johannesburg, across South Africa and Southern Africa. We supply and support a complete range of Uninterruptible Power Supplies, inverters, batteries, and solar products.
The products shown here are particularly well suited for homes, townhouse developments, farms and guesthouses. These systems should also be considered for small businesses such as restaurants, shops, medical practices, pharmacies, workshops, etc. where data capture/transfer is not necessarily critical. (For critical backup such as for servers and important computers, you should consider a UPS system.)
Individual shops in shopping centres would find these systems ideal as they can basically be installed anywhere unlike generators. Sinetech offers cost-effective, reliable and carefree back-up systems.
The advantage of these products is that you don’t have to install a noisy generator. Generators need constant refilling and maintenance and are not ideal for residential areas or for small businesses where noise and pollution from the exhaust are a problem.
When utility power returns, the whole procedure is reversed and the unit will switch back to utility power and will automatically start re-charging the batteries. Your equipment remains connected to the system even when power is restored. The whole process is fully automatic.
The amount of backup time is determined by the size of the connected battery bank and the load drawn from the system. The backup time is directly in proportion to the load drawn. The backup time is normally calculated at full load (i.e. if the system is a 2200VA system, full load is 2200VA). If you remove some of the connected load, then the backup time will be extended accordingly.
Yes, but the system has to be correctly sized to begin with. These systems are capable of bridging power outages from 2 – 24 hours or (e.g. for 2 hours per day twice a day) as the battery chargers are powerful enough to recharge the battery bank to cater for the second outage on the same day (providing there is enough time between the 2 outages – at least 4-6 hours). Again this process if fully automatic.
The smaller systems can be used as stand-alone systems or can be wired into your DB board. The larger systems can also be used as stand-alone systems but it is by far more convenient if they are hard-wired into your DB board. Sinetech will provide support, such as block diagrams, for the electrical installation.
These systems require minimum maintenance. Depending on the system chosen, the batteries are either semi sealed lead calcium batteries or fully sealed Gel batteries. Batteries are maintenance free and do not have to be filled. It is recommended that battery sets are installed in a battery cabinet and are locked in a room with ventilation, where small children do not have access. As with all batteries, these batteries can be dangerous if tampered with. Sinetech does supply complete systems with batteries and battery cabinets if required.
A UPS system is designed to backup sensitive equipment like servers, computers, medical equipment, telecommunications equipment, etc. Standard UPS systems have small internal battery sets and can only provide short backup times of approximately 5 – 10 minutes which cannot be extended as the internal battery chargers are small and can only cater for the internal battery sets they were designed for. Additional or external batteries cannot be connected to these UPS systems.
There are also long backup UPS systems available which can be supplied with external battery sets to provide backup for, usually not more than 2 hours. If the user requires longer backup than 2 hours, the system would then have to be intentionally oversized to cater for the longer backup time, which can then be extended to 4 – 6 hours. For longer backup times, UPS systems should be installed in conjunction with a generator.
In contrast, inverter based long backup systems do have a small break when they switch over to backup power (irrespective of the inverter system brand or model). The higher quality systems, which Sinetech supplies, switch over in a very short time and it is hardly noticeable. Inverter backup systems incorporate larger battery chargers which allows larger battery sets to be installed which results in much longer backup times than UPS systems.
In contrast, home long backup systems, which do have a small break when they switch over to backup power (irrespective if the inverter system, but the good quality systems have a power break during switchover which is hardly noticeable), incorporate large battery chargers which enables extra large battery sets to be installed, which results in extra long back-up times.This is not possible with UPS systems.
Firstly we recommend you read the explanation. Then make a list of exactly what appliances you want to provide backup power for. You need the appliance ratings in Watts, Amps or VA (this is usually stated on the back of the appliance on a label or in the manual). When you have this power rating, add them all together to come to a total power rating. This can be done with the help of an electrician or someone who understands these calculations.
You can then look at the different backup times provided by a particular unit. Please contact us for pricing and availability. We can arrange a trained electrician for installations in the greater Johannesburg and Pretoria areas.
The larger inverter systems (5kW, 6kW, 8kW and 10kW systems) are able to run most of the more ‘power hungry’ items. Some of the more sophisticated systems are also available in three phase up to 72kVA.
