- KEISOKU GIKEN AC source 6900S Series
Specializing in simple operation and simple specifications as the definitive low-cost power supply.
The lineup includes five models with output capacities of 500VA, 1kVA, 2kVA, 3kVA, and 5kVA. This is an AC power supply that can be used for a wide range of applications, from home appliances to aircraft power supplies.
AC source 6900S Series
Maker:
KEISOKU GIKEN
Feature
Supports wide variable range
Supports output from voltage 0 to 310V and frequency from 40 to 450Hz. It can be used in a wide range of situations, from white goods such as air conditioners, washing machines, refrigerators, and vacuum cleaners to aircraft power supplies.
Simultaneous measurement of 4 values
Frequency, voltage, current and power factor (or power) can be measured simultaneously like a power meter. In addition, we have adopted a large green LED with high visibility to make it easier to see.
Easy operation with direct keys
Other than the system keys, the buttons only call certain functions. Anyone can operate it easily without reading the instruction manual.
Resistant to inrush current
Inrush current can be supplied up to 4 times the specification. It can withstand repeated crest factors up to three times the specification.
