Model Variants
The document provides detailed tables listing various models with specific input and output voltage ranges, output current, power, efficiency, and output ripple. Models are categorized by output voltage capabilities (≤5000V and ≥6000V) and isolation types (isolated, non-isolated positive, and non-isolated negative outputs).

Connection Diagrams
Typical connection diagrams are provided for different model types, emphasizing the need for specific external connections for non-isolated models with outputs ≥6000V.

Specifications:
A high-quality ceramic capacitor of 0.1µF, 2kV is required across the output. For models with ≤5000V output, input and output grounds are not internally connected and may be connected externally. For models with ≥6000V isolated output, input terminals cannot be connected to output terminals. For ≥6000V non-isolated positive output models, an external connection using the COM output terminal to either +IN or -IN input terminals is necessary.

Mechanical Drawings:
Dimensions are provided in inches and millimeters. For ≤5000V output models, input and output grounds must not be connected anywhere in the circuit. For ≥6000V isolated output models, the output is floating. For ≥6000V non-isolated positive output models, the common output must be connected to +IN or -IN input, and the output is negative. For ≥6000V non-isolated negative output models, the common output must be connected to +IN or -IN input, and the output is positive.

Warranty and Liability:
Pico Electronics warrants its products to be free from defects in material and workmanship for one year after shipment. The warranty is limited to repair or replacement and does not cover usage outside the product's specifications. Pico assumes no liability for consequential damages or losses incurred by the purchaser or third parties. Products are not guaranteed for use in nuclear, radioactive, or space environments without consultation.

Packaging:
Products are packaged in cardboard carriers with specified dimensions.
