6.1 OVERVOLTAGE PROTECTION

The PFS front-ends provide a fixed threshold overvoltage (OV) protection implemented with a HW comparator. Once an OV condition has been triggered, the supply will shut down and latch the fault condition. The latch can be unlocked by disconnecting the supply from the AC mains or by toggling the PSON_L input

6.2 UNDERVOLTAGE DETECTION

Both main and standby outputs are monitored. LED and PWOK_L pin signal if the output voltage exceeds ±7% of its nominal voltage. Output under voltage protection is provided on both outputs. When either V1 or VSB falls below 93% of its nominal voltage, the output is inhibited.

6.3 CURRENT LIMITATION

6.3.1 MAIN OUTPUT

When main output runs in current limitation mode its output will turn OFF below 2 V but will shut down after 6 attempts. If current limitation mode is still present after the unit retry, output will continuously perform this r outine until current is below the current limitation point. The supply will go through soft start every time it retries from current limitation mode. Figure 6a. Current Limitation on V1 (Vi = 230 VAC)

Note that the read protocol may request a single byte or word. In addition, Block read commands are supported with a total maximum length of 255 bytes. See PFS Programming Manual BCA.00006 for further information.

8.18 PSMI PROTOCOL

New power management features in computer systems require the system to communicate with the power supply to access current, voltage, fan speed, and temperature information. Current measurements provide data to the system for determining potential system configuration limitations and provide actual system power consumption for facility planning. Temperature and fan monitoring allow the system to better manage fan speeds and temperatures for optimizing system acoustics. Voltage monitoring allows the system to calculate input wattage and warning of system voltage regulation problems. The Power Supply Management Interface (PSMI) supports diagnostic capabilities and allows managing of redundant power supplies. The communication method is SMBus. The current design guideline is version 2.12. The communication protocol is register based and defines a read and write communication protocol to read / write to a single register address. All registers are accessed via the same basic command given below. No PEC (Packet Error Code) is used. WRITE The write protocol used is the SMBus 2.0 Write Word protocol. All writes are 16 -bit words; byte reads are not supported nor allowed. The shaded areas in the figure indicate bits and bytes written by the PSMI master device. See PFS Programming Manual for further information. READ The read p rotocol used is the SMBus 2.0 Read Word protocol. All reads are 16 -bit words; byte reads are not supported nor allowed. The shaded areas in the figure indicate bits and bytes written by the PSMI master device. See PFS Programming Manual for further information.

8.19 GRAPHICAL USER INTERFACE

Bel Power Solutions provides with its “Bel Power Solutions I2C Utility” a Windows® XP/Vista/Win7 compatible graphical user interface allowing the programming and monitoring of the PFS1200-12-054NAH Front-End. The utility can be downloaded on: belfuse.com/power-solutions and supports Power Management Bus protocols.
