Delta Electronics DPD 301 Series DC Power Distribution Unit

Name: Delta Electronics DPD 301 Series DC Power Distribution Unit
Brand: Powerbox Australia
SKU: DPD 301
Availability: OutOfStock

The Delta DPD 301 is a 1U DC power distribution unit that takes the 48Vdc bus from a telecom power system and divides it into individually protected load branches. Each branch runs through an intelligent breaker that detects voltage, current and temperature and can be switched on and off remotely, so operators can see what every load is drawing ...

The unit fits any standard 19-inch EIA rack and takes its feed through M8 busbar screw connections. Push-in 63A and 125A frame breakers can be mixed within the 300A total, so the panel is configured to match the loads on site, and spare positions leave room to add branches later. The IMBUS and RS485 controller connections are made at the front of the unit.

Delta specifies the DPD 301 for 3G, 4G and 5G mobile sites, fixed-line networks and datacom installations, where 48Vdc equipment needs protected and monitored feeds from the power system.

Control and monitoring run through a Delta Orion Touch Controller, which provides LVLD (load low voltage disconnect), breaker ON/OFF control and breaker trip alarms. Browse our DC power systems or the complete Delta and Eltek range for rectifiers, controllers and other DC power system components.

FAQs

What is a DC power distribution unit?

A DC power distribution unit (DC PDU) divides the output of a DC power system into separately protected feeds for each load. The DPD 301 does this for 48Vdc telecom and datacom equipment, using intelligent breakers that can be monitored and switched remotely.

What input voltage does the DPD 301 accept?

40–60Vdc, with 48Vdc nominal and up to 300A maximum. The input connects through a DC busbar with M8 screws, for 35–50mm² cable.

How many breakers does the DPD 301 hold?

It is supplied as 6 x 63A + 1 x 125A, with 3 spare positions for 63A breakers. It supports up to 12 x 63A breakers, and 63A and 125A breakers can be mixed within the 300A total.

What cable sizes do the load breakers take?

0.75–16mm² for 63A type breakers and 25–35mm² for 125A type breakers. The breakers are push-in type.

Can loads be monitored and switched remotely?

Yes. The intelligent breakers provide ON/OFF control, current sensing, voltage, power and energy monitoring and breaker trip alarms, with remote control and monitoring through a Delta controller.

Does the DPD 301 support load low voltage disconnect (LVLD)?

Yes. The intelligent breakers include LVLD, controlled through a Delta Orion Touch Controller, to disconnect loads at a set voltage during battery discharge.

How does the DPD 301 connect to a controller?

Through 2 IMBUS ports and 1 RS485 port, all with front access. Remote control and monitoring run via a Delta Orion Touch Controller, which supports 2 units in serial connection.

What size is the DPD 301 and will it fit my rack?

It measures 482.6 x 44 x 410mm (W x H x D) and suits a standard 19-inch rack, taking 1U of rack space. It weighs approx. 7kg with breakers.

Does the DPD 301 have surge protection?

Yes. The SPD is rated ≥ 10kA differential-mode and ≥ 15kA common-mode. Breakers also provide overload and short circuit protection.

What environment is the DPD 301 rated for?

Operating temperature is 0 to +60°C, altitude up to 3000m and relative humidity 5–95% non-condensing. It is rated IP20, so it suits indoor equipment rooms and enclosed cabinets.

What standards does the DPD 301 meet?

It is an IEC 62368-1 compliance design and is RoHS compliant.
