It's great to see the blossoms on the trees here after
a prolonged winter. As I write this, the local Rochester
Lilac Festival is in full swing after a damp start. It's
the largest festival of its kind in North America, which began 121
years ago and continues to be inspired by the magnificent lilac
collection at Highland Park, expertly designed by Frederick Law Olmsted to seem like a natural occurrence of
trees, shrubs and flowers. 500 varieties of lilacs are now in full
bloom on more than 1,200 bushes. Highland Park has a history as
colorful as its 500 varieties of flowering shrubs.
Here at Saelig, we have not quite 500 varieties of
power supply news for you below!

Channel DC Supplies
From the basic benchtop
90W 18V/3A GWInstek workhorses to the sophisticated
rackmount programmable, LXI Certified and economical Versatile
Power BENCH XR Series. we have DC power supplies that will
give you just the right performance - at just the right price - in
small, compact designs. These VP models even feature Wireless
Digital Remote Sense!
If you need more than one voltage
(maybe a logic supply and +/- rails for an analog section) then we
can satisfy those needs too. Siglent's SPD3303X-E
Linear Programmable DC Power Supply at $389
offers three independent, isolated outputs, with a minimum
resolution of 10mV/10mA. Channels 1 and 2 can each output up to 32V
at 3.2A, while Channel 3 is designed as a logic supply, selectable
to 2.5/3.3/5V at up to 3.2A. Each output has short-circuit and
overload protection, and an intelligent temperature-controlled fan
reduces operational noise. Here's a helpful EEVblog
teardown video of the SDP3303X version (1mV/1mA control instead of the
SPD3303X-E's 10mV/10mA). Rigol's DP800 Series of linear power source systems have up to 3
outputs and 200 Watts of total power. Built in V, A, and W
measurements make power monitoring easy. In
addition, wave tracking, timing, and analysis features offer
even more ways to use the supplies.
QPX 1.2kW Dual Output DC Power Supplies offer users a
level of flexibility that cannot be achieved with conventional
laboratory power supplies. Dual isolated outputs of 600 watts each
use PowerFlex+ regulation to provide a very wide range of
voltage/current combinations with a selection of digital interfaces
offered: USB, RS232, GPIB and LXI- compliant Ethernet LAN.
Power DC Supplies
ADG-L Series of Programmable DC Power Supplies consists of
14 models with three different output powers: 4kW, 8kW and 12kW.
Utilizing PWM technology, ADG-L supplies deliver precisely
controlled, stable outputs. With CV, CC and CP modes, the ADG-L
series is ideal for Photovoltaic, Electric Vehicle, battery,
fuse/capacitor and third party laboratory testing. The 1000V High
Voltage model is especially suitable for EV-related R&D
testing, as well as product aging tests. The RoHS-compliant ADG-L
series is not only a cost-effective range but also an
environment-friendly DC power supply series. It also features
complete output protection measures, including OVP, OCP, OPP, UVP
and OTP. Preen's ADG-L series compact DC power supplies employ
DSP-based control, with the 4-12kW models available in a 3U
housing, and 24kW in 6U housing.
For even higher power, Preen's
ADG series offers output voltages up to 1600V and output
current up to 2000A. Users can select standard RS-485 interface or
optional RS-232 and GPIB. The STEP and GRADUAL modes allow easy
setup on test sequence.
We have a wide range of power
quality analyzers from the well-respected Japanese company
Hioki. Hioki's portable power meters and analyzers are best in
class power measuring instruments for measuring single to
three-phase lines with a high degree of precision and accuracy.
These comprehensive but easy-to-use power quality analyzers are
great for monitoring and recording power supply anomalies, allowing
their causes to be quickly investigated, and also for assessing
power supply problems such as voltage drops, flicker, harmonics,
and other electrical issues.
Your Own Power Supply?
Then one of our Programmable
DC Loads may be just what you need! We have a versatile
selection of loads from AIM-TTi,
Siglent's SDL1020X/SDL1020X-E loads can be set to simulate a wide
range of load characteristics with an input range of
150V/30A. There are 200W and 300W models, with a resolution
of 1mV/1mA or 0.1mV/0.1mA. Both series have adjustable
current rise times from 1mA/us to 2.5A/us. These loads have four
types of static/dynamic modes: constant current, constant voltage,
constant resistance, and constant power, as well as a CR-LED mode
designed specifically for LED driver experiments.
