Additional Information: The manual provides detailed explanations of pin connections, safety precautions, and operational guidelines to ensure proper use and integration of the power supply.

Output-Current Monitoring and Error Reset: The document outlines the procedure for resetting hardware errors in the P140R series power supply units. Errors can be reset by pressing two buttons simultaneously for at least one second or by sending a specific command sequence via the bus interface.

Bus Interface Specifications: The P140R series uses a LIN interface, requiring only one pin for communication. The interface allows addressing up to eight units and setting the unit as a master or slave.

Applications and Monitoring: The document describes how to configure and monitor units via the LIN bus interface, including switching the output voltage on or off, setting output voltage and current limits, and reading various data.

Protocol Definitions: The document details the protocol frames consistent with the LIN bus protocol, including conversion factors for calculating actual voltage and current from digital values.

Parallel Operation and Redundancy: The document explains "n+1" redundancy, where one power supply can fail without affecting the load, and the use of power transistors instead of redundancy diodes.

Hot-Swap and Thermal Load Sharing: The P140R series supports hot-swap, allowing units to be replaced during operation, and implements thermal load sharing to distribute current symmetrically among power supplies.

Glossary and References: The document includes a glossary of terms and references to additional resources, such as data sheets and safety information, available online.

Product Identification: The document describes a coding system for identifying power supply units using a 4-bit system.

Status Flags: The document lists several status flags indicating various conditions of the power supply.

Voltage and Current Measurement: The actual output voltage and current are represented by 12-bit ADC values, converted using specific conversion factors.

Extended Manual for the P140R Series ____________________________________________________________________________________ Via the bus interface (see chapter 2), you can activate or de-activate any status signal. Please note that all status signals activated are combined by a logical OR. Important Notes • When there is no primary supply available (input voltage out of range or physically disconnected), there is no power supply for the status signal transistor mentioned above. • When you connect several units in parallel, the status signal following a signal event is indeterminate. Therefore, trigger...

AC / DC POWER SUPPLY PRIMARY SWITCHED ? SINGLE OUTPUT P140R SERIES-10

Extended Manual for the P140R Series ____________________________________________________________________________________ 3.2 Hot-Swap “Hot-swap” means that any unit of an „n+1“ redundancy system may be replaced during operation. As long as you keep to the remarks in the data sheet [1] and in the safety notes [2], all units of the P140R series (with an H15 connector) are ready for hot-swap. Allow the unit a minimum cooling time of one minute before you plug it in again. 3.3 Thermal load sharing Conventional load sharing is a good way of sharing the total current symmetrically between several...
