Tech Tips

Connection, Operation

Connection of load

  • Please use a short lead wire that is sufficiently thick for the connection.
  • Please use PVC electric cable (105°C) that can fully to lerate the voltage used. It is necessary to consider current capacity, length limit of output wire by sensing (0.5 V/lead) and so on for wiring with load. Please refer to the following diagram to determine the thickness of cable.
AWG mm2 Max current (A)
18 1.1 2
16 1.3 7
14 2.1 11
12 3.3 18
10 5.3 23
8 8.4 39
6 13 67
4 21 106
2 33 170
1 42 209
1/0 53 270
2/0 67 330
3/0 85 350

Use several cables or copper bar for model over 350 A.

Parallel connection of load

Good

connection of good example

Bad

connection of bad example

A power supply has no direct branching, but the load is branched using cables.

Specifications Definitions

Unless specifically indicated, the spcifications in this catalog are values at rated output (full scale) after 2-hour warm up.

Scope of Specifications

The following specifications are applied within a range of 10 to 100% of the rated output.

  • Ripple
  • Stability
  • Variations
  • Temperature coefficient
  • Linearity of output
  • Linearity of monitor
  • Linearity of indications
Scope of Specifications

Ripple

Displays rms including high-frequency noise

Preset

The preset value does not accurately show the actual status of output. When accurate setting is required, actually output with no load and set the voltage. Also, set the current setting to the desired value by outputting with the output terminal shorted and gradually increasing current.
