PR message
Our strength is
・ Small lot production support
・ Has technical capabilities and is good for custom-designed products.
◆ Overview and features
Used for measuring current.
Due to the CT with current transformer ratios of "1000: 1" and "2000: 1", the secondary current value becomes smaller.
It is easy to use in electronic circuits.
By connecting a resistor of several Ω to the secondary side, an output voltage of several V can be obtained.
"Tokyo Seiden" is a company that designs, manufactures, and sells power transformers, power supplies, test equipment, etc.
Through manufacturing, in order to enhance the happiness of employees and the value of our customers, we set quality goals and practice PDCA activities to achieve them, and deliver better products faster and at reasonable prices.
・ Providing design and manufacture of custom products (according to customer's required specifications) (1 small lot or more)
・ Providing R & D partners.
・ In addition, we provide repair, maintenance, and calibration services.
① Application:
・ For power supply and generator characteristic evaluation
・ For discharging batteries, etc.
・ For line impedance simulator in product characteristic evaluation test
・ Electronic load for regeneration from motors, etc.
② Specifications
・ Resistance load <R load>: DC load (~ 1500Vdc, ~ 500kW), AC load (single-phase, three-phase ~ 500kW)
・ Inductive load <RL load>: ~ 750VDC, AC ~ 707VAC, ~ 100kW
・ Variable power factor load <RLC load>: Single-phase, three-phase, single-phase three-wire / three-phase switching ~ 16kVA
・ Other load devices: Line impedance device (0.19Ω / 0.23mH, etc.), electronic load (~ 270kW)
A shunt (shunt) is a resistor that is used to measure current, generally when a current is passed through a resistor and the voltage drop is measured.
It is also used as a resistance when measuring with high precision by converting current into voltage.
Renewed shunt TS series
The lineup includes voltage drop: 50 mV, accuracy: 0.2% / 0.1%, and current value: 0.5A to 10000A.
Please refer to the link below for details .
1. Overview
-In addition to the conventional TWV series "TWV-551", "TWV-552", and "TWV-1051", a new standard lineup of output voltage ~ AC20kV and capacity ~ 2.5kVA has been added.
However, when the output voltage is AC20kV, the capacity is 500VA.
・ All testers in the standard lineup are equipped with an insulation resistance test function.
-The same withstand voltage test and insulation resistance test as the conventional TWV series can be performed.
"Pass / fail judgment function by setting upper and lower limit values", "voltage compare function", "timer function", etc.
・ This series can handle output voltage ~ AC100kV and capacity ~ 5kVA.
2. 2. Use
Also called a Withstand voltage test. This test confirms that electrical equipment and electrical and electronic components have sufficient dielectric strength against the working voltage and that they do not break down.
Electrical equipment includes transformers, distribution boards, power supplies, load devices, and home appliances. ..
High frequency transformer / power inductor
Our high frequency transformers and power inductors are mounted on Toshiba Device & Storage's 1.6kW AC-DC server power reference board. The power supply achieves a conversion efficiency of 93% (Vin = 230V, 100% load) of 80Plus Platinum class in 1U size, and is configured by combining various advanced technologies.
This circuit information and design information are provided on the Web (please refer to the link page below).
In addition, our high-frequency transformers and inductors are also mounted on the next newly designed power supply board.
