The ECD1000A, a new ruggedized series from Powerbox (PRBX) is said to be designed for use in demanding industrial and ground-based military applications.
The New Released ECD1000A IP65 Rated Power Supplies Provide:
- 1000W and may be utilized with a baseplate working temperature range of -40 to +75 degrees C.
- It is housed in a metal IP65 shell with baseplate conduction cooling.
- ECD1000A is mechanically ruggedized according to the MIL-STD-810H standard complementing extremely demanding applications.
- Interior boards and components are protected with a conformal coating.
With power factor correction (PFC), the power supply runs across a broad universal input range of 85 to 305 VAC. The ECD1000A is available with an output voltage of 28VDC and is part of a series that also includes 500W and 700W versions with 12VDC and 28VDC output voltages for use in lower power distribution systems.
The The ECD1000A IP65 Rated Power Supplies is designed for high availability, short time-to-market, and compliance with commercial and military off-the-shelf (COTS/MOTS) business models.
Power Supplies: Growing Demand in Military Applications
Power supplies are needed for many military applications in order to run with little or no ventilation cooling. When we talk about harsh environments, we mean those where electronic equipment is housed in a sealed box and is used in situations like radio communication systems that are vulnerable to bad weather, outdoor access control and surveillance, and indoor equipment that must adhere to very strict noise levels.
Systems designers are driven by concerns about reliability and maintenance costs in addition to environmental regulations to avoid using fans and blowers in favor of conduction cooling housed in a box with an IP65 rating for ingress protection (dust tight and protected against water jets).
The PRBX ECD1000A Has Been Designed:
- To ensure optimal heat transfer from the dissipating components to the baseplate.
- Deliver a high level of performance within an operating temperature range of -40 to +75 degrees centigrade at the baseplate.
- Conduction cooling necessitates very specific building practices.
- A derating may be applicable, as stated in the technical specification, depending on the assembly technique and general cooling circumstances.
The product is equally well electrically ruggedized to withstand harsh transients and meet demanding EMC performance levels as required for most common defense and the more demanding industrial applications, according to the MIL-STD- 461 CE102 / RE102 and meeting the MIL-STD-1399-300, noted PRBX official release.
To cover a large range of applications, the ECD1000A operates with a wide universal input range from 85 to 305VAC (Nominal 100 to 277VAC). The unit includes PFC with a power factor of 0.98/0.95 (110VAC/230VAC).
To power internal bus distribution systems, the ECD1000A is available in a single output DC voltage of 28V/36A. Using a high efficiency topology, typical efficiency at 28V output and 230VAC input is an excellent 91%.
From defense to demanding industrial applications, the addressable range of applications requiring ruggedized power solutions is extremely large.
Accordingly, the ECD1000A series has been designed to meet higher levels of shock and vibration, it has harsh transient protection and additional EMC filtering such as specified by MIL-STD-461E CE102 / RE102, MIL-STD 1399-300A and MIL-STD-810H.
For safety, the ECD1000A has an IN/OUT isolation of 3,000VAC and IN/FG of 2,000VAC. Output isolation to FG is 500VAC. The power supply includes over current protection with auto recovery, over-voltage and over-temperature protection.
The input, output and signal are interfaced via circular MIL Spec Connectors providing extremely reliable connection and protection against moisture penetration and oxidation.
Added Interface in PRBX IP65 Rated Power Supplies:
The ECD1000A includes a Remote Control and a Power Good interface to monitor the unit whether in normal or abnormal operation. It has passed shock and vibration testing as specified in MIL-STD-810H. In that respect the products have been tested to levels far above normal operating conditions and are designed to sustain high, 20G level shocks.
More Embedded Functions
The ECDA platform includes additional embedded functions shortening the Time-To-Market for specific applications requiring different output voltages.
In its IP65 enclosure, the ECD1000A measures 204 x 326 x 50.8mm (8.03 x 12.83 x 2 inches) and weighs 3.5kg max.
Key Applications
Benefiting from a design optimized for conduction cooling, the ECD1000A is suitable for applications requiring a silent power solution such as in a control room. Equally, it is suitable for industrial applications where forced air ventilation is not possible due to environmental constraints. Attached to a chassis or cold plate, the ECD1000A can deliver impressive power levels with a very high level of reliability.
