PRODUCT DESCRIPTION
AC rack power supply
Bently Nevada 3300/12 is a AC-input rack power supply. The supply converts the selected primary input into regulated voltages for a 3300 monitoring rack and its transducers. It fits the leftmost rack position and supports up to twelve monitors. Loss of primary power can remove the machinery-monitoring function.
This base-model record identifies the AC power-supply family but does not select its primary voltage, power input module or agency option. The manufacturer lists separate low- and high-voltage input configurations. Establish the complete installed order before choosing a spare or connecting power.

AC RACK POWER SUPPLY
Integrating 3300/12
The supply converts the selected primary input into regulated voltages for a 3300 monitoring rack and its transducers. It fits the leftmost rack position and supports up to twelve monitors. Loss of primary power can remove the machinery-monitoring function.
Match the 3300 rack, primary input range, power input module and selected negative transducer voltage. A 3000-series transducer arrangement using -18 Vdc must not be casually mixed with 3300 or 7200 equipment using -24 Vdc; the manufacturer requires application review. The 3300/12 belongs with the newer SDI/DDI-compatible backplane, identified by 3300/05 rack option AA 21 through 37; it cannot simply replace a supply on an original backplane. The compatibility guide prohibits mixing old and new power/backplane generations except for its stated 3300/14 arrangement.
Install only in rack position 1 and follow the applicable power-input wiring diagram. The manufacturer strongly recommends an external annunciator on the OK relay because power or field-wiring failure can remove machinery protection. Confirm fuse and hazardous-area requirements from the installed assembly.
Features:
- Match complete order, installed input and output configuration, wiring and installation instructions
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 3300/12 AC-input rack power supply requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 3300/12 requires comparing complete order, installed input and output configuration, wiring and installation instructions. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
Match the 3300 rack, primary input range, power input module and selected negative transducer voltage. A 3000-series transducer arrangement using -18 Vdc must not be casually mixed with 3300 or 7200 equipment using -24 Vdc; the manufacturer requires application review. The 3300/12 belongs with the newer SDI/DDI-compatible backplane, identified by 3300/05 rack option AA 21 through 37; it cannot simply replace a supply on an original backplane. The compatibility guide prohibits mixing old and new power/backplane generations except for its stated 3300/14 arrangement.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 3300/12 AC-input rack power supply requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 3300/12
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
How is 3300/12 identified?
This base-model record identifies the AC power-supply family but does not select its primary voltage, power input module or agency option. The manufacturer lists separate low- and high-voltage input configurations. Establish the complete installed order before choosing a spare or connecting power. -
What is the function of this component?
The supply converts the selected primary input into regulated voltages for a 3300 monitoring rack and its transducers. It fits the leftmost rack position and supports up to twelve monitors. Loss of primary power can remove the machinery-monitoring function. -
Does the rack backplane affect replacement compatibility?
The 3300/12 belongs with the newer SDI/DDI-compatible backplane, identified by 3300/05 rack option AA 21 through 37; it cannot simply replace a supply on an original backplane. The compatibility guide prohibits mixing old and new power/backplane generations except for its stated 3300/14 arrangement. Also match the input voltage, PIM, transducer supply and installed system-monitor configuration. -
What application does it support?
The power supply converts the chosen AC source into regulated rack and transducer voltages. The complete installed arrangement must remain within the documented capacity. -
What should be checked during installation?
Install only in rack position 1 and follow the applicable power-input wiring diagram. The manufacturer strongly recommends an external annunciator on the OK relay because power or field-wiring failure can remove machinery protection. Confirm fuse and hazardous-area requirements from the installed assembly. -
Does this rack require two power supplies?
The manufacturer states that one 3300 supply supports up to twelve monitors and their associated transducers, with no second supply required in the same rack. This is not a claim of redundant power architecture. -
Is the selected input-module option the same as the output-voltage jumper?
No. The ordering option chooses the power input module arrangement. The -24 or -18 Vdc transducer output is a separate field-programmable selection that must match the installed sensors.
