PRODUCT DESCRIPTION
ESR-48/40AC telecom rectifier is a digital rectifier that converts the 85~300VAC to 53.5VDC and possesses the characters of high efficiency, high power density,walk-in start, hot-plug, complete protection, and low noise. The rectifier adopts the latest power monitoring technology, implements the function of monitoring the states of loads and the rectifier status in real time. The output voltage of the rectifier can be adjusted through the host.
Features
High efficiency: >94%
Input voltage range: 85~300VAC
Operating temperature range: -40ºC~75ºC
Total harmonic distortion(THD): ≤5%
Hot-plug
Digital control
Intelligent electric meter
Supports CAN communication
Adjustment of voltage and current
Meet RoHS requirements
Passing the TUV, CE, CB, UL certifications
Basic specifications Dimension 40.8(H)×105(W)×281(D)mm Weight ≤2kg Cooling Forced air cooling Input feature Input voltage 85~300VAC Input mode 220VAC single phase(or 110VAC dual live lines) Frequency 45~66Hz, rated: 50Hz/60Hz Maximum input current ≤19A Power factor ≥0.99 THD ≤5% Output feature Output voltage 42~58VDC, default value: 53.5VDC Output power 3000W(176~300VAC) Environmental specifications Operating temperature -40ºC~+75ºC(non-derating under 50ºC) Storage temperature 40ºC~+75ºC Relative humidity 5%~95%(non-condensing) Altitude range ≤4000m(If the altitude is within the range of 3000m to 4000m, the maximum operating temperature decreases by 1ºC as the altitude increases by 200m.) Protection Input overvoltage protection Protection point: >300VAC Input undervoltage protection Protection point: <80VAC Output overvoltage protection 58.5~60.5VDC(can be set by PMU) Output short circuit protection A long term short circuit is allowed. Overtemperature protection Protection point: ≥75ºC(167ºF)

FAQ
Are we a trader or a manufacturer?
To be exact, we are an officially authorized agent and can get in touch with the manufacturers directly to enjoy a high proportion of cost discounts.
How to pack?
Can be packaged according to customer's needs
How long is your delivery time?
If the goods are in stock, generally 5-10 days. If there is no stock and an order needs to be placed, it needs to be determined according to the delivery dates of different brands.
