CCCV4824

It regulates both voltage and current simultaneously using a true Constant-Current Constant-Voltage strategy. In normal operation it holds the programmed output voltage (CV mode, green LED); when the load demands more than the set current limit, it transitions to CC mode (yellow LED) and holds current instead, letting voltage droop. This makes it directly suitable for battery charging, LED strings, and current-limited loads without external current-sense circuitry.

Input 8–50 V DC. Output is capped by two rules: ≤ 0.9 × U_in AND ≤ U_in − 2 V (whichever is lower) — at U_in = 8 V that's ~6 V max output. Per-variant undervoltage lockout disables the device below ~8.5 V (4805) / ~13.5 V (4812) / ~26 V (4824) typ; hysteresis re-enables above ~7.5 / 13 / 25 V.

Per variant: CCCV4805 — 3 A avg / 4 A peak; CCCV4812 — 2 A avg / 3 A peak; CCCV4824 — 1.5 A avg / 2 A peak. Units may be paralleled only when each output passes through an output diode — operation without the diode is not supported. Only identical units (same part number) may be paralleled. Output diode modules are available from DPS.

The LED gives a complete status readout at a glance: green = constant-voltage mode (normal), yellow = constant-current mode (load drawing limit current), purple = input undervoltage lockout active, blue = overtemperature shutdown engaged, red = control loop out of range. Any colour other than green or yellow requires attention before the application can run correctly.

Typical 90 %, peak ~94 %. At U_in = 48 V and ≥1.5 A: CCCV4824 ~93 %, CCCV4812 ~91 %, CCCV4805 ~87–88 %. Lower step-down ratio = higher efficiency. Below ~500 mA efficiency falls steeply on all variants; avoid light-load operation if heat budget is tight.

Yes — recommended continuous output is 20–40 W depending on variant and mounting. Overtemperature trips the output off (blue LED) and the device restarts automatically when the unit cools below the re-enable threshold. No electrolytic capacitors are used, which supports long service life in hot environments.

Set at the factory, not field-adjustable on standard catalogue variants. The programming interface is described as "Factory" in the datasheet. Custom output voltages and current limits within the 0–30 V / 0–4 A envelope are available on order. For field-adjustable setpoints choose the DCP48 instead, or contact DPS to discuss programmable CCCV variants.

Yes, in principle — CCCV is the standard charge profile for both chemistries (constant current until voltage target, then constant voltage for absorption). Factory-set voltage and current limits must match the battery specification exactly. For lithium cells ensure the CV setpoint does not exceed the cell manufacturer's max charge voltage; the CCCV48xx provides no cell-level balancing or BMS function. Contact DPS to specify the correct setpoints for your battery pack.

Yes — DPS customises output voltage, output current limit, undervoltage lockout threshold, and connector style for production volumes. An engineering fee applies; contact DPS to scope your variant. Factory programmability infrastructure is in place, which keeps customisation lead times short.
