Detailed Information
1. PSVD6UU48P1200-X Input Voltage Operation Range.

The PSVD6UU48P1200-X steady state operation voltage is 18V to 48V,continuously work up to 50V Input line.

1.1 Low Line Turn-on and Turn-off Limits

To avoid Turn-on and Turn-off glitch the unit have about 3.5V Hysteresis. The Turn-on threshold isunder 20V and turn- off below 18V.
Those limits can be adjusted, contact Factory for more information.

2. Outputs Voltage Regulation

The PSVD6UU48P1200-X contains accurate internal sense lines to keep output voltage
at less than 1.5% regulation for all Line/ Load and temperature range (see Table 2).

2.1. Sense Lines

Current Sharing forVS1, VS2 and VS3

Sense Lines are provided for VS1, VS2 and VS3 output to compensate line voltage drop.
Sense Lines proper connection is shown in Figure 1.
Each VSx output has its own Sense Lines, additional common Sense RTN Line is provided
for all VSx Outputs (VITA 62 Standard).
Contact Factory for Sense configuration different than the VITA 62 standard.

3.1 Current Sharing (Optional)

Current sharing is available for VS1, VS2 and VS3 outputs. Load share pins should be connectedfor Hiccup synchronization. 3.3V Aux and ±12V Aux can be safely paralleled.
To obtain a good current sharing the following steps should be taken• Connect hiccup pins of desired outputs to guarantee simultaneously Turn-on ofparalleled outputs.
• Connect Sense Line of both paralleled outputs to the same point.
•Make sure Power traces are as identical as possible for both current sharing outputs.
