Sleek Networks' decision to choose an advanced modular UPS pays dividends, now and in the future
When hosting company Sleek Networks created a new Tier III data centre in late 2009, it chose Leeds, West Yorkshire, as its base - proactively advocating that London is not the only place to source quality hosting. For its fast-growing business, it based critical power protection on the PowerWAVE 9000DPA from Uninterruptible Power Supplies Limited (UPSL) – an advanced system which offers flexible system expansion, in incremental steps. Nick Wil...
MAX8922L: Li+ battery charger has GSM test mode in a 6mm2 TDFN
Maxim introduces the MAX8922L, a 30V, single-input lithium-ion (Li+) charger with a 2.3A GSM test mode.
