UBA5 Fixed Supply


UBA5 with UL and CSA approved power supplies.

SKU: N/A Category:

For Canadians

Although the standard UBA power supply has CE and S Mark, it does not have a UL or CSA approval.
If you have a Canadian shipping address, if you require UL or CSA approval, or if you want to use a fixed supply, then we offer the following UBA5s with fixed supplies:

UBA5 with a Fixed 15V 80W

Works with batteries up to 11.1V for li-ion (9V for NiCd/NiMH).
Choose this if the UBA5 will be used exclusively on low voltage batteries.
Approvals: UL, CSA, CE, efficiency level IV and RoHS

Fixed 19V 120W

Works with batteries up to 14.4V for li-ion (12V for NiCd/NiMH or SLA).
This supply is ideal if your batteries are 12V or lower (4S for lithium).
Approvals: UL, CSA, CE, efficiency level IV and RoHS

Fixed 24V 120W

Works with batteries up to 18.5V for li-ion (16V for NiCd/NiMH).
For batteries below 12V the UBA5 cuts back the maximum charge current.
Approvals: UL, CSA, CE, efficiency level IV and RoHS

1 The small power supply is for powering the UBA5 only, it does not provide the charge current.

2 The maximum battery pack voltage depends on the battery chemistry.


  • All UBA5s come with a serial and USB cable, battery cables, software, manual, and unlimited technical support from our engineering department.
  • All UBA5s can discharge at up to 3A per channel (2.4A for UBA5-60V/UBA5-70V) with a 45W per channel limit
  • All UBA5s can test battery packs down to a single cell, any chemistry
  • All power supplies are universal input, i.e. they work in North America, Europe, or Asia.
