MBE1200-1T24

The MBC1200 / MBE1200 Series of AC-DC power supplies provides a steady 1200 W of regulated DC power through 180-305 VAC and 1000 W through 85-137 VAC input voltage ranges in a single output of 24 or 48 VDC, offering 12 and 5 VSB standby outputs and a full set of protection features. 

The MBC1200 / MBE1200 Series is available in three compact 1U height compatible packages; one, enclosed with a built-in front mounted pair of fans and two (available only 24 V variant), U-shaped chassis with or without protective cover, to facilitate system integration. 

The MBC1200 / MBE1200 Series supports digital power management over the Power Management Bus communications protocol. Multiple units may be connected in parallel for redundancy and / or higher power, enabled with the internal OR-ing and current sharing functions.

MBC1200 / MBE1200 Series 

5 

The MBC1200 / MBE1200 Series does support communication according to the Power Management Bus 1.2 protocol via SDA, SCL and #SMBALERT signals as defined in the SMBus Specification version 2.0. 

The power supply shall not load the SMBus if it has no input power (SCL & SDA lines should go to High-Z). 

The pull-up resistors (2.2 k Ω ) for these signals shall be external to the power supply and referenced to an external +3.3 V bus voltage. 

The DSP circuits inside the power supply are powered by the standby output. 

The Power Management Bus is active whatever input power is applied to the power supply or a parallel redundant power supply in the system, provided that their 12VSB are connected in parallel. 

Maximum speed of SMBus is 100 kHz. 

The ADDR0 and ADDR1 signals, are inputs to the power supply that control the Power Management Bus address assigned to the power supply. 

On the system side, the ADDR0 and ADDR1 signals will either be connected to return through a 1 k Ω pull-down resistor or connected to +3.3 V external bus voltage through a 1 k Ω pull-up resistor. 

The address shall be derived from the logic of this pin as indicated on Outline Drawing and Connections section. The power supply is a slave only on SMBus device. 

For a comprehensive description of MBC1200 / MBE1200 Series Power Management Bus management, do refer to the application note, “MBC1200 / MBE1200 Series Power Management Bus Mgt”. Examples of 1200 W Series parameters available through communication bus are: 

- Input voltage status 

- Output voltages +V1 measured value 

- Output current on +V1 measured value 

- Current sharing status 

- Thermal health measured value 

- Fan health status 

- Power-On / Working hours 

- Product information 

- Status information 

Failures shall be reported by Power Management Bus for all failure types: 

- Fan fault 

- Protections failure (OV, OC, OT) 

- Voltages out of specification

* When V1 is On, a P_OK low may indicates V1 under voltage condition. When two 1200 W models operate in parallel, P_OK low in one unit indicates that it is not sharing the expected amount of current (current sharing fault). A 3.3 k Ω internal pull up to a 3.3 V internal reference voltage is used; do not add any other external pull up. 

** The 5VSB outputs of two or more 1200 W models operating in parallel, cannot be connected in parallel in turn, since doing so results in power supplies damage. 

*** The 12VSB outputs of two or more 1200 W models operating in parallel can be connected in parallel in turn, taking into account that the maximum available power will not be higher of a single operating power supply one.
