Meggitt Vibro Meter RPS 6U rack power module

Core functions and positioning

RPS 6U is a dedicated power supply unit for VM 600 series racks, with core functions designed around "stable power supply, high reliability, and flexible adaptation", as follows:

Multi output voltage supply: Provides three DC power supplies of+5V DC,+12V DC, and -12V DC for all cards in the rack (such as MPC 4 monitoring card) to meet the power supply needs of different cards, with output currents of 35A, 6A, and 2A respectively, and a total rated power of 300W;

Redundant deployment capability: Supports parallel installation of 1-2 modules. In the event of a single module failure, redundant modules automatically take over power supply to avoid system power outages, especially suitable for critical equipment monitoring scenarios that require high power continuity;

Wide input and protection design: Supports AC or DC wide range input (such as AC 90~264V adaptive, DC 18~145V model adaptation), integrated overvoltage protection (+5V output protection threshold 5.9~6.7V), short circuit protection (electronic current limiting, continuous short circuit without damage), to cope with power fluctuations in industrial sites;

VME compatibility: fully compliant with the VME bus specification, directly connected to the VM 600 rack backplane through two connectors, without the need for additional wiring, simplifying installation;

Low loss and temperature adaptability: Only 1%/℃ power reduction within the range of 60-70 ℃, reducing performance degradation in high-temperature environments and adapting to industrial high-temperature scenarios.

Electrical parameters and performance indicators

（1） Core electrical parameters

Parameter category specification requirements

Output characteristics -+5V DC: rated output of 35A, voltage stability under load ≤ ± 0.2%, ripple (20MHz bandwidth) ≤ 50mVpp;

-+12V DC: rated output of 6A, voltage stability under load ≤ ± 0.2%;

--12V DC: rated output 2A, voltage stability under load ≤ ± 0.2%;

-Overvoltage protection: The+5V output factory is set to 5.9-6.7V, and other outputs default to overvoltage protection.

The input characteristics are divided into two types: AC/DC, and the specific range depends on the model (such as AC type 90~264V adaptive, DC type 18~32V/38.4~57.6V, etc.); AC type supports frequency fluctuations of 48-65Hz, with an efficiency of ≥ 75% (AC type) and ≥ 70% (DC type).

The power outage tolerance supports short-term power outages without resetting MPC 4 cards, and the tolerance time is related to the number of cards and power modules:

-2 MPC 4 boards: 1 module can withstand 190ms, 2 modules can withstand 250ms;

-12 MPC 4 cards: 1 module can withstand 10ms, and 2 modules can withstand 20ms.

Model classification and adaptation scenarios

RPS 6U is classified into different models based on input power type (AC/DC) and input voltage range. Different models are suitable for different industrial power supply scenarios. The specific classification is as follows:

Model Type Specific Model Rated Input Voltage Input Voltage Range Adaptation Scenarios

DC input type RPS 6U 24 DC 24V DC 18~32V DC Low voltage DC power supply scenario (such as vehicle mounted, small equipment)

RPS 6U 48 DC 48V DC 38.4~57.6V DC Industrial Standard 48V DC System

RPS 6U 72 DC 72V DC 57.6-100V DC medium voltage DC power supply scenario (such as large industrial equipment)

RPS 6U 110 DC 110V DC 80~145V DC High Voltage DC Power Supply Scenario

AC input type RPS 6U AC 110/230V AC 90~264V AC (adaptive) universal AC power supply scenario, compatible with global voltage standards

RPS 6U AC (Special) 115V AC 90~132V AC Specific Area 115V AC System

Special adaptation: The AC type also supports 178-264V DC input, achieving "AC/DC dual compatibility" and further enhancing scene adaptability.

Rear panel and installation configuration

RPS 6U requires a dedicated rear panel for power input and protection. Different panels are compatible with different input types and functional requirements. The core panel types and characteristics are as follows:

Panel type, model number, core function, adaptation scenario

Standard DC panel 200-582-920-01h single channel DC screw terminal input, with backplane connection for ordinary DC power supply scenarios

Dual DC input panel 200-582-990-01h, two independent DC terminal inputs, critical scenario where dual DC power redundancy is required for parallel backplane connection

Industrial environment with grounded DC panel 200-582-922-01h standard DC terminal+M.A.L.T. grounding terminal requiring strengthened grounding protection

Standard AC panel 200-582-910-02h AC socket+fuse+filter universal AC power supply scenario

Scenario where AC panel with switch 200-582-911-02h AC terminal+power switch+fuse requires manual control of power on/off

Dual AC redundant panel 200-582-960-03h with two AC sockets and automatic switching circuit for AC power redundancy, automatic switching in case of faults

AC+DC hybrid panel 200-582-970-01h AC socket+DC terminal, independently connected to the backplane and compatible with AC/DC input in flexible scenarios

Installation note: All rear panels are pre installed with cables, which can be directly connected to the rack backplane without the need for on-site wiring; DC input needs to distinguish between positive and negative poles, while AC input needs to confirm voltage level and frequency compatibility.

Ordering Information and Additional Instructions

（1） Core ordering parameters

Power module selection: It is necessary to specify the "model+input type+order number", for example:

24V DC input: model RPS 6U 24 DC, order number 200-582-200-01h;

110/230V AC input: model RPS 6U AC, order number 200-582-500-01h;

Note: "h" in the number represents the hardware version, minor changes do not affect interchangeability.

Rear panel selection: Choose according to input type and protection requirements, for example, choose 200-582-960-03h for dual AC redundant scenarios, and 200-582-922-01h for strengthened grounding DC scenarios.

（2） Key precautions

Power matching: Calculate the total power consumption based on the number of cards in the rack, ensuring that it does not exceed the rated power of RPS 6U (300W). For example, for 12 MPC 4 cards, priority should be given to redundant deployment;

Temperature management: During installation, it is necessary to reserve heat dissipation space to avoid modules being placed in close proximity to high heating equipment. For environments above 60 ℃, attention should be paid to power derating (1%/℃);

Redundant configuration: When deploying redundancy, it is necessary to use RPS 6U modules of the same model to ensure consistent output characteristics and avoid uneven load;

Compliant use: Only applicable to VM 600 series racks, prohibited for use in other non compatible systems to avoid damage caused by electrical mismatch.
