Used TDK-Lambda A.L.E. Systems Model 402S high-voltage capacitor-charging power supply removed from retired equipment.
The manufacturer label identifies this unit as:
Model: 402S-18KV-POS-1663V
TDK-Lambda part number: 00487184
Revision: C
Serial number: 18A0336C
Rated output: 18 kV DC
Output polarity: Positive
AC input: 180–264 VAC
Input frequency: 50/60 Hz
Input configuration: Three-phase
Front-panel configuration: S-series remote-control model
The 1663V suffix is retained exactly as printed on the manufacturer label. It appears to identify a special factory configuration or option; no unsupported interpretation of that suffix is being made.
The 402 series is designed for high-voltage capacitor charging and may also be configured for certain continuous-DC applications. TDK-Lambda specifies the standard 402 platform at 4,000 joules per second average capacitor-charging power, up to 5,000 joules per second peak, and 4 kW continuous DC power. The 402S version has status indicators and a power switch but requires operation through its rear remote-control interface. �

Testing status
This unit has not been tested.
No attempt has been made to:
Apply three-phase input power
Enable the remote-control interface
Test the interlock circuit
Measure high-voltage output
Test capacitor-charging operation
Test the unit under load
Confirm calibration or long-term performance
It is being sold as a used, untested high-voltage power supply.
Physical condition
The unit shows normal wear from prior installation and removal, including:
Scratches and scuffs
Black marks and residue on the enclosure
Rack-mount wear
General cosmetic wear from use and storage
The visible tamper seal appears present, but no warranty or representation is made regarding the internal condition of the unit.

Safety notice
This equipment can produce lethal high voltage. It must only be installed, connected, and tested by qualified personnel familiar with three-phase and high-voltage power systems.
The manufacturer requires a properly connected load, grounding, interlock system, and remote-control arrangement. The 180–264 VAC configuration uses three AC lines at L1, L2, and L3 plus protective earth; no neutral is required for the standard 200–240 VAC configuration. �
