Buy BP-103-20: power supply marine equipment, load and reserve

BP-103-20 is selected for power supply marine or industrial equipment class 24 V. For the purchase, the input network, the allowable voltage of each consumer and the load in the operating modes are important. This information allows you to agree on a specific block and backup scheme before ordering.

What to buy under the designation BP-103-20

This is a source of unstabilized power supply. The current manufacturer's manual for the BP-103-20 indicates the output range of 17.4-31.2 V DC. Therefore, the recording of “24 V equipment” is not sufficient in itself: the permissible range of the connected device must correspond to the agreed scheme.

Full designation matters. The same manual provides BP-103 and Fort PSU-103-5 with other load parameters. When ordering, save the "-20" and marking of the proposed instance; the characteristics of the neighboring model do not transfer to the selected position.

Short table for harmonization

Parameter BP-103-20	Manual, version 2.3
Main entrance	220 V AC, 50/60 Hz; 110 V optional configuration
Output	17.4–31.2 In DC, unstabilized
Nominal load current	Not more than 20 A
Nominal power output	Not more than 400 W
Standby source	24V battery; range in manual 18–31.2V
Connected loads	Four connection points, load agreed for a common block

The table helps to select a position for discussion; the passport of the supplied configuration and consumer requirements remain part of the approval. On the manufacturer’s web page, the output range is indicated in rounded form, so use the manual edition and the instance documentation for accurate selection.

Consumption is considered by working regimes

In the statement it is useful to divide the reception, transmission, start-up and other modes, if they have the equipment. Write down the permissible voltage, current and power on the passports of consumers. The number of outputs does not mean four independent sources of 20 A.

If several devices work at the same time, the supplier needs their composition and modes. This way you can check the load by the constraints of the selected unit and determine whether power supply separation is required. The universal list of "two-way radio, AIS, receiver - exactly fit" is not assigned here.

Battery reserve and battery charge – different tasks

The manual BP-103-20 directly separates power supply from charge: this unit does not charge the battery. If the circuit provides a reserve from the battery, tell us which charger is used and which battery is installed. The lack of charger cannot be compensated by the backup input of power supply alone.

For a separate charge problem, our catalogue has CH-105. It is selected by battery and power grid. The presence of both positions in the catalog does not mean a ready-made universal set: the joint scheme is coordinated with the data of the equipment and batteries.

What to say when replacing the old block

Attach the nameplate of the old source, photos of installed equipment and a list of consumers. Separately mark the input network, reserve, alarm, available space and document requirements. When replacing, it is important to keep the necessary functions of the workplace, not just the similar name of the output voltage.

“Needs BP-103-20 for [equipment/ship]. The main network is [value], the reserve is [description]. Consumers and their modes are attached. The number is [number], the receipt is [city]. Please confirm the configuration, allowable load, kit and documents.”

The current availability, cost and delivery conditions are confirmed in the quotation. The photo from the catalog shows the product, but not the remainder and composition of a particular batch.

Order and place of receipt

In the delivery request, specify the city and address: Moscow, St. Petersburg, Novosibirsk or another point in Russia and Kazakhstan. For the batch, add the number for each configuration. Availability, cost, composition and term confirmed in the quotation.

BP-103-20 in the power supply statement of the working post

Planned repair of equipment in Magnitogorsk is more convenient to start with the list of consumers, the existing source and mode of operation of the post. If the BP-103-20 receives supplies in Beloretsk for another facility, keep its separate load and reserve. The general power supply class record does not replace the permissible parameters of each device. The quotation should have a complete configuration of the block, documents and connection boundaries; check the scheme and installation agreed as a separate scope of work.

Questions before ordering

Does the BP-103-20 charge a backup battery?

Nope. In the Power Supply Manual, the equipment and battery charge are separated; a suitable separate device is required to charge.

Four exits make 20 each.

Four connection points do not turn a block into four independent sources. The load is checked for the common device on the passports of consumers.

How to order a configuration for a 110V network?

Configuration 110B is agreed separately; it cannot be assumed by the generic name BP-103-20.

Materials for approval of the kit

Primary documents: BP-103 / BP-103-20, version 2.3, table 1; Azu-105 / Azu-105-24, version 3.0, table 1. Also available page BP-103-20 manufacturer. Appointment HERCULES-10: publication of the manufacturer "Unicon". The parameters and documents of the supplied configuration are agreed separately.
