Power distribution unit Rittal DK 7859.080, Modular PDU, Max current 16 A

The Rittal DK 7859.080 Modular PDU is a compact power distribution unit intended for installation in racks and enclosures where a maximum current of 16 A is required. Designed for tidy power management, the device provides several modular outlet positions to connect equipment in server rooms, telecom racks and industrial control cabinets. Its format lets technicians organise power feeds close to the mounted devices and maintain safe access during servicing.

Advantages

This Modular PDU supports a maximum current of 16 A and offers modular outlet positions for flexible configuration. The product’s form factor is suitable for mounting in standard racks and enclosures, allowing space-efficient placement and better cable routing. It is engineered to facilitate routine maintenance and to centralise power distribution within cabinets, reducing the need for ad-hoc extension leads and improving operational order.

Suitable for

• Server rooms and data cabinets where compact, local power distribution is required
• Telecommunications racks and network cabinets
• Industrial control cabinets and electrical enclosures
• Environments requiring easy access to multiple modular outlets for maintenance or equipment changes

When it may not be suitable

This PDU is rated for a maximum current of 16 A; it may not be suitable for installations that require higher continuous currents or three-phase power. It is intended for mounting in racks or enclosures, so standalone floor or bench applications without a compatible mounting option may require a different type of power distribution unit.

Key specifications

• Maximum current: 16 A
• Form factor: modular PDU designed for rack/enclosure mounting
• Number of modular outlet positions: multiple configurable slots for outlet modules
• Application environment: server rooms, telecom racks, industrial control cabinets
• Mounting: designed for installation within racks or enclosures

How to use

Install the modular PDU inside a compatible rack or enclosure according to the cabinet manufacturer’s mounting guidelines. Fit the required outlet modules into the available positions, connect the inlet to an appropriate supply feed rated for 16 A, and route equipment power cords to the modular outlets. Ensure that all connections are made with the cabinet power switched off and that wiring meets local electrical codes. Verify load distribution so the aggregated current draw does not exceed 16 A.

What to consider before purchase

• Confirm that the maximum current of 16 A meets your total equipment load requirements
• Check that the PDU form factor and mounting style are compatible with your rack or enclosure
• Ensure the required type and number of modular outlet modules are available and compatible
• Verify local electrical regulations and required inlet/supply connection types

Usage recommendations

Distribute high-draw devices across multiple PDUs if aggregate current approaches the 16 A limit, and arrange outlet modules to separate critical systems from less critical loads. Periodically inspect connections and mounting integrity during scheduled maintenance to maintain reliable power distribution.
