Falcon Electric Offers Pre-Configured NEMA
3R/4 Enclosures with SSG UPSs
Falcon Electric, Inc. has released
NEMA 3R and 4 enclosures with Falcon’s
1 kVA to 3 kVA SSG-RP series and SSG
series 1.5 kVA to 3 kVA wide temperature UPSs. The on-line double-conversion
UPSs are UL, cUL and CE-listed to operate between -20°C to 55°C (SSG Industrial series) and -30°C to 65°C (SSG Ultra
Wide Temperature series).
These systems are typically found in
many industries such as oil & gas, communications, power generation, utility
and transportation applications. For the
oil & gas industry, these enclosures are found at well-head sites,
along oil transmission lines and at refineries.
Inside the powder-coated enclosure with forced air cooling, the
UPS is designed to swing-out 90° so the user can control the UPS
via the front panel of the UPS. Users can order an optional front
panel that locks or one that simply secures the panel shut. The
internal SSG series UPS can be pre-configured to support domestic
and global applications, as the SSG is available in both 120 VAC
and 230 Vac (220/230/240 VAC) models. In addition, all models
feature auto-sensing frequency, matching output and input.
For generator applications, the SSG series can be programmed
to “fix” the frequency on the output at 50 Hz or 60 Hz, so the
fluctuating frequency from an auxiliary generator-set does not
affect the UPS’s ability to act as a bridge when transferring to the
generator during a power outage.
The SSG series includes an RS-232 and USB interface, a cable
and a Falcon UPSilon software driver, which can be configured to
shut down a number of operating systems. For industrial applications, Falcon offers a dry-contact communications option, a secure
IPv4 and IPv6-based SNMP/HTTP option as well as a MODBUS
communications option so that if the UPS is on battery, low battery or experiences any internal failure, the network monitoring
system will display the UPS condition in the network monitoring
system’s main console or graphical user interface (GUI).
Power-One’s High Efficiency Power Supply with
Integrated Battery Back-Up Circuit
Power-One, Inc. has released 450 W and 700 W high efficiency
power supply/battery back-up units for use in servers and data
centers. The Power-One power supplies, SPAFCBK-02G (450 W)
and SPAFCBK-03G (700 W), have been designed based on the
Open Compute Project specifications.
The power supplies combine a 450 W or 700 W platinum efficiency rated AC-DC power supply with a 48 VDC battery backup circuit, all in one compact design. Both versions are highly
efficient (more 94 percent efficiency) and the power supply has
been certified to 80-Plus Platinum level efficiency. They operate
from a 277 VAC input voltage source that allows the server to
be powered directly from one-phase of the high voltage 3-phase
input power distribution network. Designing the power supply for
277 VAC per the Open Compute Project specifications eliminates
an expensive site transformer, and is critical to the goal of increasing the power efficiency and reducing the overall carbon footprint
of the data center.
With the power supply designed at better than 94 percent
efficiency, less energy is wasted within the server and less
energy is consumed in the overall cooling infrastructure. The
integrated 48 V battery back-up circuit eliminates the need
for inefficient UPS systems and allows for a localized, scalable
power back-up infrastructure.
Small in Size, Huge in Overcurrent Protection
Schurter offers a range of surface mount chip fuses, USF 0402,
USF 0603, and USF, USFF USI and
UST 1206, and MGA to provide
overcurrent protection in dense
secondary circuits such as those
found in consumer electronics such
as battery operated handheld and
portable electronic devices, such
as laptops, cell phones, GPS systems and many other devices that
have demand for increasingly smaller components.
The range of fuses is offered with quick, super quick acting and
time-lag characteristics. The current ratings in the quick and super
quick acting fuses range from 0.05 A to 6.3 A, while the time-lag
UST 1206 has current ratings ranging from of 7 A to 25 A. Rated
voltage ranges from 32 to125 VAC and 63 to125 VDC. Each fuse
series boasts performance characteristics such as low voltage drop
and high breaking capacity.
A letter marking on each fuse indicates its current rating to
ensure tracking of the proper fuse through the production process. The fuses are UL 248-14 approved and carry cURus approval.
They also hold a Free of CCC certificate from China. Terminals are
either tin or gold-plated copper alloy. The chip fuses come packaged in tapes of 1,000, 5,000 or 15,000 pieces on reels.
Schaefer Introduces Rack Mount Configurations
For Raptor Series COTS/MOTS Converters
Schaefer, Inc. has released
19 inch rack mount configurations for its Raptor series
of military power supplies.
The Raptor’s construction
and high reliability make it
a choice for harsh military
applications such as shelters,
armored vehicles, avionics,
naval and open air applications.
The Raptor series’ output voltage range can provide DC outputs
from 12 VDC to 52.5 VDC or 270 VDC, with power ratings from
1,200 W to 3,360 W. Single and three-phase input ranges span
from 88 VAC to 265 VAC. Other input or output voltages are available upon request. The series specifies high efficiency (85 percent
nominal) and high power factor correction.
The series meets MIL-STD-810C/D/E for operating temperature
conditions, vibration, and shock and also meets other MIL-STD461C/462C ratings for EMI, Navy MIL-STD-1399 and aircraft electrical power MIL-STD-704D, and environmental test methods.
The Rackmount Raptor’s protection package features input
AC circuit breakers, input over/under voltage protection, output
current limit, output over voltage protection, low output voltage
alarm and thermal protection with auto recovery.
