Portable high-precision power supply for data recovery
It is known that a stable power supply is an insurance of
successful data recoveries. This high-precision power supply
was designed to meet the need of professional data recovery
industry.
The rapid development of digital devices effectively
promotes the development of the power system. On the other
hand, data recovery - a particular application field - has
more specific requirements for the stability of power
supply. SD portable high-precision power supply for data
recovery can be used to replace the traditional desk-top
computer power supply used in data recovery industry and
hard disk repair, making it a perfect match with the trend
of the door-to-door service needs.
The features of ‘SD high-precision power supply’
A must-have for data recovery - it was acknowledged by
senior data recovery engineers that power supply plays a key
role in the process of recovering data. And directly affects
the success rate. Especially with disk capacity getting
larger, disks with high density require strictly to work
with stable power supply. What’s more, data recovery
high-precision power supply is able to maintain the
stability of heads via increasing immediate voltage of disk.
Taking WD 500GB drive for example, if the disk suffers from
a power shortage, the head of it will click when accessing
data at a high speed; and if the drive runs into bad track
which leads to repeated accesses, poor power supply will not
be able to live through but end up with no responding.
Compact and cost-effective, the size of SD high-precision
power supply is a little bigger than general Smartphone and
the whole set weighs about 0.2kg, therefore, it is
convenient to take it with you in the pocket, it is the
lightest high-precision power in existing market. Data
recovery engineers usually employ piles of tools which
occupy lots of desk space, SD high-precision power supply
takes this point into consideration, with compact design
users will hardly notice it’s there.
Portable - general ATX power supply is of cumbersome shape,
while ‘SD high-precision power supply’ is able to work for
data recovery the moment it is connected to power adaptor of
laptop. It makes the data recovery faster and more
professional. When engineers go to provide door to door
service, it is going to distinguish you from others. As a
result, your professional image is enhanced.
High efficiency and easy operation - It adopts the latest
advanced power module group from Texas Instrument, which is
consistent with the build-in power supply of SD DATA
COMPASS.
It was said that a sparrow may be small but it has all the
vital organs. Small and complete, fast and time-saving,
high-precision power developed by SD perfectly meets the
requirements of current customer. It will step up the
existing working efficiency of data recovery, and be of a
good help for you.
The power cable is made of high purity of multi-rope 0.75mm²
copper wire, and the socket as well as the connector adopts
gilding material. There are various plugs and ready
interfaces for 4P / SATA/ disk drive / soft drive, all the
connectors have past a 5000-time wearing tests.

Main technique parameters:
1. Input D.C regulated voltage power supply: voltage
19V/current 3.16 A/ input plug with excircleΦ5.5mm and inner
diameterΦ2.0mm
(Voltage and current range respectively from 18V-23V and
3A-4A, clients may choose any D.C regulated voltage power
supply according to the range.)
2. Output D.C voltage: 5V/12V/accuracy 4%
3. Output current averages: 5V1.5A、12V1.5A, peak value current
protection in 2.6A／50ms-1.5s
4. Output D.C voltage ripple: under50mV
5. Relative surrounding humidity: 30-90%
6. Circuit temperature shut-down temperature: inside
temperature 50 centigrade
7. 0.6s
Auto power-on warning tone1.2s /manual power-on warning-tone
0.8s /power-off warning tone 0.6s
8. Sensitivity protection
01) Real-time protection of both input Overvoltage
undervoltage remains in 10ms. And output overcoltage in 10
ms too
02) When starting output undervoltage, undervoltage Delayed
protection should remains in 1.5ms, 1.5s later keep
real-time protection of output undervoltage in 80s.
03) When starting Output current, overcurrent delayed
protection should be kept in 1.5s, 1.5s later real-time
protection of output overcurrent in 50ms.
9. Attentions:
01) Aluminum alloy skull should handle with care, preventing
damages from falling or knocking
02) The skull is linked to the power cathode of internal
circuit, so damages caused by short-cut between load and
skull should be noted.
03) Temperature state of the skull varies from the changing
of the load weight and time. And the temperature of skull
sometimes may come up to 55 centigrade or above.
