The previous table shows the LED indicators for each PD
product type.
For example, the PD690SRD includes the following LED indicators-
690V, 440V, 230V, 120V, 50V.
Battery low indication
All PD products support the battery low LED, which is illuminated
when the battery voltage is low.
PD440S / PD690S
On these PD products the "High voltage" LED is ON when the live
voltage is present at the voltage output terminals. If the loading
impedance of the voltage indicator (at the output terminals) is less
than 1kΩ then the "High voltage" LED will start flashing.
PD230SRD / PD440SRD / PD440SRDX / PD690SRD
On these PD products there are multiple LED to indicate the voltage
at the PD output terminals when a voltage indicator is under test
at the terminals. Refer to the graph of typical output voltage under
various voltage indicator load conditions on the specification page.
Also refer to the "PD Output voltages table" under section 2.2. The
LED indication will depend on the loading impedance of the voltage
indicator under test as well as the PD output voltage steps in the
"PD Output voltage table". If the loading impedance of the voltage
indicator (at the output terminals) is less than 1kΩ then the "50V"
LED will start flashing.
Voltage Output Mode (AC / DC)
AC LED and DC LED indicate the PD output voltage mode.
