SUVTP MBP PART NO REQUIRED UP TO FOUR UNITS

[Anonymous user]

Dear Team,

As per below screen shot, it is confirm that the APC Smart VT can run upto Four units in parallel, we failed to find out Parallel MBP for Four units, we can find Parallel MBP for Three Units, please advise the part number of Parallel MBP which can support Four units.

This MBP is required for Smart VT 10KVA, 15KVA, 20KVA & 30KVA.40KVA

Kind Regards

Zakir

I think you'd want to look at the following SKUs:

SUVTOPT009 - Parallel Communication Kit

SUVTOPT010 - MBP Panel CAN I/O kit with cable

G35TOPT011 - Baying Kit

As I am based in NAM, you may need to verify with sales in your region to make sure the part numbers are the same. We were able to dig up SBPAR10K20H-WP which is a 400V panel but I hope this helps get you started in the right direction.

Thanks for the reply but the question arises, how can we configure 4 SUVT units in parallel as the below mentioned Maintenance Bypass Panels support "upto three units only"

SBPAR10K20H-WP : BYPASS PANEL for SUVT10kva-20kva UPTO THREE UNITS

SBPAR30K40H-WP : BYPASS PANEL for SUVT30kva-40kva UPTO THREE UNITS

Sorry about that - I guess the answer is that the SUVT / G3500 units ARE capable up to four in parallel but the tricky part is that from what I've found we do not have a standard

MBP part number for four. I believe this will require interaction with the APC Configuration Team which can happen through your regional sales team. In summary, sounds like it needs to be a special order configuration and there is no simple part number or answer to provide.

Thanks for the reply, just want to confirm the working of SUVTOPT010, and if we use till three units of SUVT in parallel and are not going for closed couple formation, can the part SUVTOPT009 and SBPAR10K20H-WP/SBPAR30K40H-WP only can make the combination (i.e without SUVTOPT010) if not, kindly help to elaborate the exact working of SUVTOPT010 in this formation, as we have installed few units of SUVT in parallel only using communication kit.

here is what I can tell you from one of our 3 phase power support individuals in NAM:

SUVTOPT010 is the CAN I/O board that can be installed in the maint bypass for parallel operations. SUVTOPT009 is the parallel communications cables / box kit part of which is installed directly at each ups to be paralleled.

SBPAR30K40H-WP Is the EMEA version of the parallel capable maint bypass panel, here in NAM (especially if you

want four units in parallel), we go through the CEG team to spec out the requirements for the MBP and have it built. Due to low quantity of sales for four parallel on SUVT/G3500, we stopped carrying an active SKU and rely on CEG for those types since they as are so infrequent.

Basically SUVTOPT010 can be added to an existing system to make it parallel capable but the problem with adding after the fact is that the MBP sold with these systems is generally 1 or 2 utility inputs (dual feed). The Q1 is ups input isolation, Q3 is the maintenance bypass to tie utility directly to customer loads and Q2 is UPS output isolation. In a parallel group, you need a Q1 for each ups in the group i.e. -Q1a Q1b Q1c Q1d with four UPS's same for Q2 i.e. Q2a Q2b Q2c Q2d while Q3 only requires the 1 switch / breaker and you add a Q4 as system output isolation. This way, you can isolate individual UPS units and still provide protected power to loads or isolate entire system as necessary.

If they you wish to go with parallel systems, then I would highly recommend you go through your regular sales channels in combination with the CEG team in your region to have an appropriate three or four unit parallel capable MBP spec'd out as adding the capability after the fact allows for many errors and problems

that will be encountered. As well as with single units, MBP is not 100% necessary although always a good idea but with parallel it is very necessary

as isolating individual units can cause drop load situations and increased risk for same if no parallel MBP is used.
