The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) made by American Power Conversion (APC). [1] Most of the units have a SmartSlot (with the exception of SC and SMC series) which accepts an optional interface card providing features ranging from network connectivity to temperature and humidity monitoring. [2]
APC Smart-UPS is a line of smaller units intended for home and office use, available as floor-standing and rackmount versions. With the exception of the Smart-UPS Online series (SURT and SRT models), Smart-UPS units are line-interactive UPS systems, running their outputs off the inverters only when the grid power is unavailable.
A UPS designed for powering DC equipment is very similar to an online UPS, except that it does not need an output inverter. Also, if the UPS's battery voltage is matched with the voltage the device needs, the device's power supply will not be needed either. Since one or more power conversion steps are eliminated, this increases efficiency and ...
Apcupsd, short for APC UPS daemon, is a utility that runs on Linux, UNIX, macOS and Windows. [1]: 1, 8–9 It allows the computer to interact with APC UPSes. Apcupsd also works with some OEM-branded products (e.g. Hewlett-Packard) manufactured by APC. [1]: 7 [2] [3] Apcupsd is a free software equivalent of the APC's proprietary PowerChute software.
Borg-Warner R-11 overdrive - 3-speed manual transmission with electric overdrive Ford used them up until 1975 in trucks. Borg-Warner T-50 transmission — 5-speed longitudinal manual - used by GM in its RWD H-Body cars and a few other limited light duty applications from 1976 to 1978;
Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power. An Automatic Transfer Switch (ATS) is often installed where a backup generator is located, so that the generator may provide temporary electrical ...
Basically there are two types of motor vehicle transmissions: Manual – the driver has to perform each gear change using a manually operated clutch; Automatic – once placed in drive (or any other 'automatic' selector position), it automatically selects the gear ratio dependent on engine speed and load
The standard transmission was a three-speed manual with a column shift, but there were also four- and five-speed manuals and a three-speed automatics, with floor-mounted shifters optional. [6] The automatic transmission was not available in heavier duty models such as the 1300D and the rare 1500D.
