COMPONENT
PV-JM807 · PV-JM807 module junction box
Zhejiang Jiaming Tianheyuan Photovoltaic Technology ↗A 1000 V DC module junction box from Jiaming Tianheyuan. Its 6A family row depends on the diode fitted, so agree the diode and current definition with Jiaming first.
PV-JM807 is a component for PV module assembly with a published 1000 V DC rating. For 1500 V, higher current or a certified build, ask Jiaming for the matching model and its TÜV annex.
General illustration of module assembly equipment, not a photograph of this model. Ask the manufacturer for current photographs and layout drawings of the configuration offered.
START WITH YOUR PRODUCTION TASK
Agree the diode and current conditions, get the controlled drawing and certificate annex, then prove the ribbon connection and enclosure seal on your own module.
SOURCE-LINKED DATA
Published specifications
Values below are published by the manufacturer, each with the date its source was checked. Ask for the figures that apply to your configuration and material in the quotation.
The manufacturer has not published a complete specification table for this entry. Request the delivered material specification, drawing where applicable and lot acceptance requirements.
01 · Manufacturer information
What PV-JM807 is and where the 6A figure comes from
PV-JM807 sits in Jiaming's PV junction-box category. The specification lists 1000 V DC and carries a TÜV label. Jiaming adds that fitting a different diode changes the box's maximum operating current, yet the page names no diode options or test conditions.
In the family table, 6A appears under a Chinese heading that translates as junction-temperature current, with no further definition. Ask Jiaming for the rated-current designation, the diode type and the temperature it refers to. Compare that figure with your module's short-circuit current once you have it in writing.

PV-JM807 published data and what to ask for
| Entry | Published value | Ask Jiaming for |
|---|---|---|
| Rated voltage | 1000 V DC | The approved voltage scope of your variant; no 1500 V version is listed. |
| Contact resistance | ≤0.5mΩ | Test method, connection and measurement conditions. |
| Safety class | Class II | Construction details and current documents. |
| Temperature range | −40 to +85°C | Rating conditions for the assembled box. |
| Cable sizes | 4mm² and 2.5mm² | Full cable and termination specification. |
| Enclosure protection | IP65, mated | The lid, cable, connector and seal build that achieves it. |
| Housing and contacts | Black PPO/PA; tin-plated copper | Approved material grade and change control. |
| Flame class | UL94-V0 | Material thickness and the matching test report. |
| Family row | 6A; TÜV label | Current definition, diode type and certificate annex. |

Four interfaces the data table leaves open
Ribbon and terminal
Jiaming mentions quick ribbon installation and a reinforced connection. Ask for terminal and ribbon dimensions and the soldering or clamping instructions written for this box.
Diode and heat
Ask for the diode maker and type, how the current is defined and the temperature behind it. Treat 6A as tied to that one diode; a different diode or module current needs its own rating.
Mated enclosure and wiring
Specify cable build and length, exits, lid and the actual connector pair. The IP65 figure applies to the mated assembly Jiaming defines.
Bonding to the module
Share your glass or backsheet surface and layout. Request the approved bonding and sealing materials, surface preparation and cure and release times for PV-JM807.

From catalogue choice to an approved PV-JM807 build
Get the controlled variant package
Ask for the model revision, outline and terminal drawing, diode and wiring bill of materials, safety documents and current certificate annex, plus the name of the site that produces and releases the boxes.
Clear up conditional entries
Settle the 6A heading and its conditions, the contact-resistance method and the mated IP65 build. Ask Jiaming to state in writing that the variant suits your module.
Build a traceable sample
Follow the approved ribbon, bonding and sealing steps. Record component lots, materials and settings, then inspect connection, polarity and enclosure against agreed criteria.
Test component and module
Agree electrical and environmental checks for the box and the finished module, with preparation and pass criteria. Ask for model-level certificate coverage and real results to go with the TÜV label and the standards role.
Freeze what passed
Keep the accepted drawings, sample lots, test records and instructions on file. Require technical approval before any change of diode, polymer, wiring, connector, site or process on repeat orders.

PV-JM807 questions buyers ask
Is 6A the module short-circuit current limit?
The table heading gives it no such meaning. Ask Jiaming for the rated-current conditions and the exact diode configuration.
Is the box rated IP68?
Jiaming lists IP65 for the mated box. For IP68 or offshore use, ask for a model documented to that level.
Is there a TÜV certificate number?
The page shows a TÜV label only. Ask for the current certificate with holder, factory and configuration coverage.
Do the group's valve licences apply here?
They belong to the valve business. Request the material and product documents for PV-JM807 itself.
Can we switch to another diode later?
Jiaming says the diode sets the maximum current, so any change needs approval against the qualified configuration and fresh test documents.
