Meggitt Vibro meter RPS6U (VM600/VM600Mk2) rack power supply

Meggitt Vibro meter RPS6U (VM600/VM600Mk2) rack power supply

Product Overview and Applications

Output:+5 VDC, ± 12 VDC, with a maximum total output power of 330 W for the new version and 300 W for the old version.

There are three types of input versions: AC input version, RPS6U-24 DC (24 VDC input), and RPS6U-110 DC (110 VDC input).

Rack configuration mode

Single power supply (1 RPS6U): Power supply for the entire rack module, ambient temperature ≤ 50 ℃; No redundancy.

Dual power supply - redundant mode: Two RPS6Us, one faulty and the other bearing 100% of the entire rack load, improving system availability; Only suitable for environments ≤ 50 ℃.

Dual power supply - non redundant mode: no fault backup, only used in high temperature environments above 50 ℃ to compensate for power supply high temperature derating.

Note: In dual power redundancy mode, the total current is limited by the capacity of a single power supply; The maximum load distribution for non redundant dual power sources is 80/20.

The rack back panel is equipped with a power detection relay to provide feedback on the working status of RPS6U; The rack can be additionally equipped with ASPS auxiliary sensor power supply, which outputs+24 VDC to external sensors and signal conditioning hardware.

Protection characteristics

Overvoltage protection: output overvoltage automatically locks off;

Short circuit and overload: automatic recovery;

High temperature power derating: natural convection heat dissipation starts to derate above 50 ℃; Under forced air cooling conditions, there is no need to reduce the rating.

Power Description: 330W is the total power of all output combinations, and each output cannot run at full capacity at the same time. For example, if+5V runs at 50A (267.5W), the total load of ± 12V cannot exceed 62.5W.

Status indicator LED

IN (green): Input main power is normal; VM600 old version AC version is labeled AC, DC version is labeled DC, and Mk2 is uniformly labeled IN.

+5V (yellow):+5V output is normal.

+12V (yellow):+12V output is normal.

12V (yellow): 12V output is normal.

Interface and Machinery

Backplane connectors: 2 high current DIN41612 H15 connectors, compatible with rack VME backboards.

Weight: Approximately 2.4 kg; VM600Mk2 front panel made of bare aluminum material; VM600 is a painted panel with identical hardware and electrical components, only differing in appearance labeling.

The circuit board is equipped with a three proof coating for resistance to moisture, dust, and chemical environments; Indoor use only.

Certification: CE, EAC; EMC EN55022 Class B； Safety standard UL/CSA/EN 60950-1; RoHS； Overvoltage category OVC II.

Power interruption tolerance (power down hold)

Allow brief interruption of input power supply, the rack module will reset after timeout; The higher the load, the shorter the allowed interruption time. Example: For a single AC power supply, the maximum 10% load is 190 ms, while for a 100% full load, it is only 10 ms; for a dual AC power supply, it can reach up to 20 ms at full load. The DC version has a shorter holding time.

Ordering Information

1) RPS6U power supply body

Model VM600Mk2 Material Number VM600 Material Number Input

RPS6U‑AC 200‑582‑500‑12h 200‑582‑500‑02h AC

RPS6U‑24DC 200‑582‑200‑12h 200‑582‑200‑02h 24 VDC

RPS6U‑110DC 200‑582‑600‑12h 200‑582‑600‑02h 110 VDC

The suffix h represents the hardware minor version and does not affect interchangeability.

2) Rear panel of matching rack

There are a total of 13 specifications, including DC input series, AC input series, and AC+DC hybrid input;

DC type: no built-in fuse, external circuit breaker protection must be added; Supports single channel DC and dual channel DC redundant inputs, with some equipped with MALT protective grounding terminals.

AC type: built-in fuse/filter, divided into with switch, without switch, single AC input, dual AC redundant input (120V/230V).

Some models support ASPS auxiliary sensor power supply; There are CE standard version and CSA North American version.

Rear panel suffix NHh, N=version, H=major version change, h=minor change.

3) AC power cable

Multiple plugs are available (EU European standard, UK British standard, US American standard, JP Japanese standard, Swiss SEV, etc.); The DC power version does not come with a matching power cord.

Key points to note in system design

Power selection criteria: RPS6U quantity (1/2 unit), single power version (300W old version/330W new version), dual power working mode (redundant/non redundant), ambient temperature, actual module power consumption of the rack.

When the number of rack modules exceeds 10, it is necessary to separately calculate the power consumption of the entire machine and confirm the power configuration.

The AC input panel comes with a built-in fuse; There is no built-in protection for DC input, and an external circuit breaker must be configured.

When the AC version power supply is paired with a specific DC type back panel, the AC power supply body can also be directly connected to DC voltage for use.
